Left-libertarianism


Left-libertarianism, also known as egalitarian libertarianism, left-wing libertarianism or social libertarianism, is a political philosophy and type of libertarianism that stresses both individual freedom and social equality. Left-libertarianism represents several related yet distinct approaches to political and social theory. In its classical usage, it refers to anti-authoritarian varieties of left-wing politics such as anarchism, especially social anarchism, whose adherents simply call it libertarianism. In the United States, it represents the left-wing of the libertarian movement and the political positions associated with academic philosophers Hillel Steiner, Philippe Van Parijs and Peter Vallentyne that combine self-ownership with an egalitarian approach to natural resources. This is done to distinguish libertarian views on the nature of property and capital, usually along left–right or socialist–capitalist lines.
While maintaining full respect for personal property, left-libertarians are opposed to capitalism and the private ownership of the means of production. Other left-libertarians are skeptical of, or fully against, private ownership of natural resources, arguing in contrast to right-libertarians that neither claiming nor mixing one's labor with natural resources is enough to generate full private property rights and maintain that natural resources should be held in an egalitarian manner, either unowned or owned collectively. Those left-libertarians who support private property do so under different property norms and theories such as mutualism, or under the condition that recompense is offered to the local or even global community such as the Steiner–Vallentyne school.
Market-oriented left-libertarianism, including Pierre-Joseph Proudhon's mutualism and Samuel Konkin III's agorism, appeals to left-wing concerns such as class, egalitarianism, environmentalism, gender, immigration and sexuality within the paradigm of free-market anti-capitalism. Although libertarianism in the United States has become associated to classical liberalism and minarchism, with right-libertarianism being more known than left-libertarianism, political usage of the term until then was associated exclusively with anti-capitalism, libertarian socialism and social anarchism and in most parts of the world such an association still predominates.

Definition

People described as being left-libertarian or right-libertarian generally tend to call themselves simply libertarians and refer to their philosophy as libertarianism. In light of this, some political scientists and writers classify the forms of libertarianism into two or more groups such as left-libertarianism and right-libertarianism to distinguish libertarian views on the nature of property and capital. In the United States, proponents of free-market anti-capitalism consciously label themselves as left-libertarians and part of the libertarian left.
Traditionally, libertarian was a term coined by the French libertarian communist and Le Libertaire editor Joseph Déjacque to mean a form of left-wing politics that has been frequently used to refer to anarchism and libertarian socialism since the mid- to late 19th century. Sébastien Faure, another French libertarian communist, began publishing a new Le Libertaire#Le Libertaire |Le Libertaire in the mid-1890s while France's Third Republic enacted the so-called villainous laws which banned anarchist publications in France.
As a term, left-libertarianism has been used to refer to a variety of different political economic philosophies emphasizing individual liberty. With the modern development of right-libertarian co-opting the term libertarian in the mid-20th century to instead advocate laissez-faire capitalism and strong private property rights such as in land, infrastructure and natural resources, left-libertarianism has been used more often as to differentiate between the two forms, especially in relation to property rights.
While right-libertarianism refers to laissez-faire capitalism such as Murray Rothbard's anarcho-capitalism and Robert Nozick's minarchism, socialist libertarianism "view any concentration of power into the hands of a few as antithetical to freedom and thus advocate for the simultaneous abolition of both government and capitalism". According to Jennifer Carlson, right-libertarianism is the dominant form of libertarianism in the United States while left-libertarianism "has become a more predominant aspect of politics in western European democracies over the past three decades". Socialist libertarianism has been included within a broad left-libertarianism in its original meaning. Left-libertarianism also includes "the decentralist who wishes to limit and devolve State power, to the syndicalist who wants to abolish it altogether. It can even encompass the Fabians and the social democrats who wish to socialize the economy but who still see a limited role for the State".
According to the textbook definition in The Routledge Companion to Social and Political Philosophy, left-libertarianism has at least three meanings, writing:
In its oldest sense, it is a synonym either for anarchism in general or social anarchism in particular. Later it became a term for the left or Konkinite wing of the free-market libertarian movement, and has since come to cover a range of pro-market but anti-capitalist positions, mostly individualist anarchist, including agorism and mutualism, often with an implication of sympathies not usually shared by anarcho-capitalists. In a third sense it has recently come to be applied to a position combining individual self-ownership with an egalitarian approach to natural resources; most proponents of this position are not anarchists.

The Stanford Encyclopedia of Philosophy distinguishes left-libertarianism from right-libertarianism, arguing:
Libertarianism is often thought of as 'right-wing' doctrine. This, however, is mistaken for at least two reasons. First, on social—rather than economic—issues, libertarianism tends to be 'left-wing'. It opposes laws that restrict consensual and private sexual relationships between adults, laws that restrict drug use, laws that impose religious views or practices on individuals, and compulsory military service. Second, in addition to the better-known version of libertarianism—right-libertarianism—there is also a version known as 'left-libertarianism'. Both endorse full self-ownership, but they differ with respect to the powers agents have to appropriate unappropriated natural resources.

Terminology

As a term, left-libertarianism is used by some political analysts, academics and media sources, especially in the United States, to contrast it with the libertarian philosophy which is supportive of free-market capitalism and strong private property rights, in addition to supporting limited government and self-ownership which is common to both libertarian types.
Peter Vallentyne describes left-libertarianism as the type of libertarianism holding that "unappropriated natural resources belong to everyone in some egalitarian manner". Similarly, Charlotte and Lawrence Becker maintain that left-libertarianism most often refers to the political position that holds natural resources are originally common property.
Followers of Samuel Edward Konkin III, who characterized agorism as a form of left-libertarianism and strategic branch of left-wing market anarchism, use the terminology as outlined by Roderick T. Long, who describes left-libertarianism as "an integration, or I'd argue, a reintegration of libertarianism with concerns that are traditionally thought of as being concerns of the left. That includes concerns for worker empowerment, worry about plutocracy, concerns about feminism and various kinds of social equality".
Anthony Gregory maintains that libertarianism "can refer to any number of varying and at times mutually exclusive political orientations". He describes left-libertarianism as maintaining interest in personal freedom, having sympathy for egalitarianism and opposing social hierarchy, preferring a liberal lifestyle, opposing big business and having a New Left opposition to imperialism and war. Although some American libertarians such as Walter Block, Harry Browne, Leonard E. Read and Murray Rothbard may reject the political spectrum whilst denying any association with both the political right and left, other American libertarians such as Kevin Carson, Karl Hess, Roderick T. Long and Sheldon Richman have written about libertarianism's left-wing opposition to authoritarian rule and argued that libertarianism is fundamentally a left-wing position. Rothbard himself previously made the same point, rejecting the association of statism with the left.

Philosophy

While all libertarians begin with a conception of personal autonomy from which they argue in favor of civil liberties and a reduction or elimination of the state, left-libertarianism encompasses those libertarian beliefs that claim the Earth's natural resources belong to everyone in an egalitarian manner, either unowned or owned collectively.
Many left-libertarian schools of thought are communist and market abolitionist, advocating the eventual replacement of money with labor vouchers or decentralized planning. Contemporary left-libertarians such as Hillel Steiner, Peter Vallentyne, Philippe Van Parijs, Michael Otsuka and David Ellerman believe the appropriation of land must leave "enough and as good" for others or be taxed by society to compensate for the exclusionary effects of private property. Socialist libertarians such as anarchists and libertarian Marxists promote usufruct and socialist economic theories, including collectivism, communism, mutualism and syndicalism. They criticize the state for being the defender of private property and believe capitalism entails wage slavery.
Joseph Déjacque was the first to formulate libertarian ideas under the term libertarian. Later philosophers on the left would go onto adding detail to his political philosophy to study and document attitudes and themes relating to stateless socialism. In Déjacque's case, it was called libertarian communism.

Personal autonomy

Left-libertarianism such as anarchism envisages freedom as a form of autonomy which Paul Goodman describes as "the ability to initiate a task and do it one's own way, without orders from authorities who do not know the actual problem and the available means". All anarchists oppose political and legal authority, but collectivist strains also oppose the economic authority of private property. These social anarchists emphasize mutual aid whereas individualist anarchists extol individual sovereignty.

Civil liberties

Left-libertarians have been advocates and activists of civil liberties, including free love and free thought. Free love appeared alongside anarcha-feminism and advocacy of LGBT rights. Anarcha-feminism developed as a synthesis of radical feminism and anarchism and views patriarchy as a fundamental manifestation of compulsory government. It was inspired by the late-19th-century writings of early feminist anarchists such as Lucy Parsons, Emma Goldman, Voltairine de Cleyre and Virginia Bolten. Advocates of free love viewed sexual freedom as a clear, direct expression of individual sovereignty and they particularly stressed women's rights as most sexual laws discriminated against women: for example, marriage laws and anti-birth control measures. Like other radical feminists, anarcha-feminists criticize and advocate the abolition of traditional conceptions of family, education and gender roles. Free Society was an anarchist newspaper in the United States that staunchly advocated free love and women's rights while criticizing comstockery, the censorship of sexual information. Anarcha-feminism has voiced opinions and taken action around certain sex-related subjects such as pornography, BDSM and the sex industry.
Free thought is a philosophical viewpoint that holds opinions should be formed on the basis of science, logic and reason in contrast with authority, tradition or other dogmas. In the United States, free thought was an anti-Christian, anti-clerical movement whose purpose was to make the individual politically and spiritually free to decide on religious matters. A number of contributors to Liberty were prominent figures in both free thought and anarchism. Catalan anarchist and free-thinker Francesc Ferrer i Guàrdia established modern or progressive schools in Barcelona in defiance of an educational system controlled by the Catholic Church. Fiercely anti-clerical, Ferrer believed in "freedom in education", i.e. education free from the authority of the church and state. The schools' stated goal was to "educate the working class in a rational, secular and non-coercive setting".
Later in the 20th century, Austrian Freudo-Marxist Wilhelm Reich, who coined the phrase sexual revolution in one of his books from the 1940s, became a consistent propagandist for sexual freedom, going as far as opening free sex-counseling clinics in Vienna for working-class patients. According to Elizabeth Danto, Reich offered a mixture of "psychoanalytic counseling, Marxist advice and contraceptives" and "argued for sexual expressiveness for all, including the young and the unmarried, with a permissiveness that unsettled both the political left and the psychoanalysts". The clinics were immediately overcrowded by people seeking help. During the early 1970s, the English anarchist and pacifist Alex Comfort achieved international celebrity for writing the sex manuals The Joy of Sex and More Joy of Sex.

State

Many socialist left-libertarians are anarchists and believe the state inherently violates personal autonomy. Anarchists believe the state defends private property which they view as intrinsically harmful as this strongly prevents removal of illegitimate authority through inspection and vigilance. Robert Paul Wolff has argued that "since 'the state is authority, the right to rule', anarchism which rejects the State is the only political doctrine consistent with autonomy in which the individual alone is the judge of his moral constraints".
Market-oriented left-libertarians argue that so-called free markets actually consist of economic privileges granted by the state. These left-libertarians advocate for free markets, termed freed markets, that are freed from these privileges. They see themselves part of the free-market tradition of socialism.
Although mainly related to libertarianism in the United States, Objectvism and right-libertarianism, a minimal state or minarchism has also been advocated by left-libertarians, either as a path to anarchy or as an end in itself. Some left-libertarians have proposed or supported a minimal welfare state on the grounds that social safety nets are short-term goals for the working class and believe in stopping welfare programs only if it means abolishing both government and capitalism. Other left-libertarians "prefer that corporate privileges be repealed before the regulatory restrictions on how those privileges may be exercised".

Property rights

Socialist left-libertarians are opposed to private property and the private ownership of the means of production, supporting instead common or social ownership, or property rights based on occupation and use. Other left-libertarians believe that neither claiming nor mixing one's labor with natural resources is enough to generate full private property rights and maintain that natural resources ought to be held in an egalitarian manner, either unowned or owned collectively.
It has been argued that socialist values are incompatible with the concept of self-ownership, when this concept is considered "the core feature of libertarianism" and socialism is defined as holding "that we are social beings, that society should be organised, and individuals should act, so as to promote the common good, that we should strive to achieve social equality and promote democracy, community and solidarity". However, it has also been argued that "property rights do not pass judgment as to what rights individuals have to their own person to the external world" and that "the nineteenth-century egalitarian libertarians were not misguided in thinking that a thoroughly libertarian form of communism is possible at the level of principle".

Economics

Left-libertarians like anarchists, libertarian Marxists and market-oriented left-libertarians argue in favor of libertarian socialist economic theories such as collectivism, communism, mutualism and syndicalism. Daniel Guérin wrote that "anarchism is really a synonym for socialism. The anarchist is primarily a socialist whose aim is to abolish the exploitation of man by man. Anarchism is only one of the streams of socialist thought, that stream whose main components are concern for liberty and haste to abolish the State".

Schools of thought

Anarchism

Anarchism is a political philosophy that advocates stateless societies characterized by self-governed, non-hierarchical, voluntary institutions. It developed in the 19th century from the secular or religious thought of the Enlightenment, particularly Jean-Jacques Rousseau's arguments for the moral centrality of freedom.
, who has been described as an early philosophical anarchist
As part of the political turmoil of the 1790s and in the wake of the French Revolution, William Godwin developed the first expression of modern anarchist thought. According to anarchist Peter Kropotkin, Godwin was "the first to formulate the political and economical conceptions of anarchism, even though he did not give that name to the ideas developed in his work". Godwin instead attached his ideas to an early Edmund Burke. He is generally regarded as the founder of philosophical anarchism, arguing in Political Justice that government has an inherently malevolent influence on society and that it perpetuates dependency and ignorance.
Godwin thought the proliferation of reason would eventually cause government to wither away as an unnecessary force. Although he did not accord the state with moral legitimacy, he was against the use of revolutionary tactics for removing the government from power, rather he advocated for its replacement through a process of peaceful evolution. His aversion to the imposition of a rules-based society led him to denounce, as a manifestation of the people's "mental enslavement", the foundations of law, property rights and even the institution of marriage. He considered the basic foundations of society as constraining the natural development of individuals to use their powers of reasoning to arrive at a mutually beneficial method of social organization. In each case, government and its institutions are shown to constrain the development of our capacity to live wholly in accordance with the full and free exercise of private judgment.
, the first self-described anarchist
In France, revolutionaries began using anarchiste in a positive light as early as September 1793. Pierre-Joseph Proudhon was the first self-proclaimed anarchist and is often described as the founder of modern anarchist theory. He developed the theory of spontaneous order in society in which organisation emerges without a central coordinator imposing its own idea of order against the wills of individuals acting in their own interests, saying: "Liberty is the mother, not the daughter, of order". Proudhon answers his own question in What Is Property? with the famous statement that "property is theft". He opposed the institution of decreed property in which owners have complete rights to "use and abuse" their property as they wish and contrasted this with usufruct or limited ownership of resources only while in more or less continuous use. Proudhon wrote that "Property is Liberty" because it was a bulwark against state power.
Proudhon's opposition to the state, organized religion and certain capitalist practices inspired subsequent anarchists and made him one of the leading social thinkers of his time. However, French anarchist Joseph Déjacque castigated Proudhon for his sexist economic and political views in a scathing letter written in 1857. He argued that "it is not the product of his or her labour that the worker has a right to, but to the satisfaction of his or her needs, whatever may be their nature". Déjacque later named his anarchist publication Libertaire, Journal du mouvement social which was printed from 9 June 1858 to 4 February 1861. In the mid-1890s, French libertarian communist Sébastien Faure began publishing a new Le Libertaire while France's Third Republic enacted the so-called villainous laws which banned anarchist publications in France. Libertarianism has frequently been used as a synonym for anarchism since this time, especially in Europe.
publication in New York City
Josiah Warren is widely regarded as the first American anarchist and the four-page weekly paper he edited during 1833 called The Peaceful Revolutionist was the first anarchist periodical published, an enterprise for which he built his own printing press, cast his own type and made his own printing plates. Warren was a follower of Robert Owen and joined Owen's community at New Harmony, Indiana. Josiah Warren termed the phrase "Cost the limit of price", with "cost" referring not to monetary price paid, but the labor one exerted to produce an item. Therefore, "e proposed a system to pay people with certificates indicating how many hours of work they did. They could exchange the notes at local time stores for goods that took the same amount of time to produce". He put his theories to the test by establishing an experimental "labor for labor store" called the Cincinnati Time Store where trade was facilitated by notes backed by a promise to perform labor. The store proved successful and operated for three years after which it was closed so that Warren could pursue establishing colonies based on mutualism. Warren said that Stephen Pearl Andrews' The Science of Society, published in 1852, was the most lucid and complete exposition of Warren's own theories. American individualist anarchist Benjamin Tucker argued that the elimination of what he called "the four monopolies"—the land monopoly, the money and banking monopoly, the monopoly powers conferred by patents and the quasi-monopolistic effects of tariffs—would undermine the power of the wealthy and big business, making possible widespread property ownership and higher incomes for ordinary people, while minimizing the power of would-be bosses and achieving socialist goals without state action. Tucker influenced and interacted with anarchist contemporaries—including Lysander Spooner, Voltairine de Cleyre, Dyer Lum and William Batchelder Greene—who have in various ways influenced later left-libertarian thinking.
The Catalan politician Francesc Pi i Margall became the principal translator of Proudhon's works into Spanish and later briefly became president of Spain in 1873 while being the leader of the Democratic Republican Federal Party. For prominent anarcho-syndicalist Rudolf Rocker: "The first movement of the Spanish workers was strongly influenced by the ideas of Pi y Margall, leader of the Spanish Federalists and disciple of Proudhon. Pi y Margall was one of the outstanding theorists of his time and had a powerful influence on the development of libertarian ideas in Spain. His political ideas had much in common with those of Richard Price, Joseph Priestly , Thomas Paine, Jefferson, and other representatives of the Anglo-American liberalism of the first period. He wanted to limit the power of the state to a minimum and gradually replace it by a Socialist economic order". Pi i Margall was a dedicated theorist in his own right, especially through book-length works such as La reacción y la revolución in 1855, Las nacionalidades in 1877 and La Federación in 1880.
In the 1950s, the Old Right and classical liberals in the United States began identifying as libertarians in order to distance themselves from modern liberals and the New Left. Since this time, it has become useful to distinguish this modern American libertarianism which promotes laissez-faire capitalism and generally a night-watchman state from anarchism. Accordingly, the former is often described as right-libertarianism or right-wing libertarianism while synonyms for the latter include left-libertarianism or left-wing libertarianism, libertarian socialism and socialist libertarianism.

Classical liberalism and Georgism

Contemporary left-libertarian scholars such as David Ellerman, Michael Otsuka, Hillel Steiner, Peter Vallentyne and Philippe Van Parijs root an economic egalitarianism in the classical liberal concepts of self-ownership and appropriation. They hold that it is illegitimate for anyone to claim private ownership of natural resources to the detriment of others, a condition John Locke explicated in Two Treatises of Government. Locke argued that natural resources could be appropriated as long as doing so satisfies the proviso that there remains "enough, and as good, left in common for others". In this view, unappropriated natural resources are either unowned or owned in common and private appropriation is legitimate only if everyone can appropriate an equal amount or the property is taxed to compensate those who are excluded. This position is articulated in contrast to the position of right-libertarians who argue for a characteristically labor-based right to appropriate unequal parts of the external world such as land. Most left-libertarians of this tradition support some form of economic rent redistribution on the grounds that each individual is entitled to an equal share of natural resources and argue for the desirability of state social welfare programs.
proposed the abolition of all taxes except those on land value
Economists since Adam Smith have opined that a land value tax would not cause economic inefficiency, despite their fear that other forms of taxation would do so. It would be a progressive tax, i.e. a tax paid primarily by the wealthy, that increases wages, reduces economic inequality, removes incentives to misuse real estate and reduces the vulnerability that economies face from credit and property bubbles. Early proponents of this view include radicals such as Hugo Grotius, Thomas Paine and Herbert Spencer. but the concept was widely popularized by the political economist and social reformer Henry George. Believing that people ought to own the fruits of their labor and the value of the improvements they make, George was opposed to tariffs, income taxes, sales taxes, poll taxes, property taxes and to any tax on production, consumption or capital wealth. George was among the staunchest defenders of free markets and his book Protection or Free Trade was read into the United States Congressional Record.
Early followers of George's philosophy called themselves single taxers because they believed the only economically and morally legitimate, broad-based tax is on land rent. As a term, Georgism was coined later, although some modern proponents prefer the less eponymous geoism, leaving the meaning of geo- deliberately ambiguous. Earth Sharing, geonomics and geolibertarianism are used by some Georgists to represent a difference of emphasis or divergent ideas about how the land value tax revenue should be spent or redistributed to residents, but all agree that economic rent must be recovered from private landholders. Within the libertarian left, George and his geoist movement influenced the development of democratic socialism, especially in relation to British socialism and Fabianism, along with John Stuart Mill and the German historical school of economics. George himself converted George Bernard Shaw to socialism and many of his followers are socialists who see George as one of their own. Individuals described as being in this left-libertarian tradition include George, Locke, William Ogilvie of Pittensear, Paine, Spencer and more recently Baruch Brody, Ellerman, James O. Grunebaum, Otsuka, Steiner, Vallentyne and Van Parijs, among others. Roberto Ardigò, Hippolyte de Colins, George, François Huet, William Ogilvie of Pittensear Paine, Spencer and Léon Walras are left-libertarians also seen as being within the left-liberal tradition of socialism.
While socialists have been hostile to liberalism, accused of "providing an ideological cover for the depredation of capitalism", it has been pointed out that "the goals of liberalism are not so different from those of the socialists", although this similarly in goals has been described as being deceptive due to the different meanings liberalism and socialism give to liberty, equality and solidarity. Liberal economists such as Léon Walras considered themselves socialists and Georgism has also been considered by some as a form of socialism. The idea that liberals or left-libertarians and state socialists disagree about means rather than ends has been similarly argued by Gustave de Molinari and Herbert Spencer. According to Roderick T. Long, Molinari was the first theorist of free-market left-libertarianism. Molinari has also influenced left-libertarian and socialists such as Benjamin Tucker and the Liberty circle. Philosophical anarchist William Godwin, classical economists such as Adam Smith, David Ricardo, Thomas Robert Malthus, Nassau William Senior, Robert Torrens and the Mills, the early writings of Herbert Spencer, socialists such as Thomas Hodgskin and Pierre-Joseph Proudhon, social reformer Henry George and the Ricardian/Smithian socialists, among others, "provided the basis for the further development of the left libertarian perspective". According to Noam Chomsky, classical liberalism is today represented by libertarian socialism, described as a "range of thinking that extends from left-wing Marxism through to anarchism". For Chomsky, "these are fundamentally correct" idealized positions "with regard to the role of the state in an advanced industrial society".
Geolibertarianism is a political movement and ideology that synthesizes libertarianism and geoist theory, traditionally known as Georgism. Geolibertarians generally advocate distributing the land rent to the community via a land value tax as proposed by Henry George and others before him. For this reason, they are often called single taxers. Fred E. Foldvary coined geo-libertarianism in an article so titled in Land and Liberty. In the case of geoanarchism, a proposed voluntaryist form of geolibertarianism as described by Foldvary, rent would be collected by private associations with the opportunity to secede from a geocommunity and not receive the geocommunity's services if desired. The political philosopher G. A. Cohen extensively criticized the claim, characteristic of the Georgist school of political economy, that self-ownership and a privilege-free society can be realized simultaneously, also addressing the question of what egalitarian political principles imply for the personal behaviour of those who subscribe to them. In Self-Ownership, Freedom, and Equality, Cohen argued that any system purporting to take equality and its enforcement seriously is not consistent with the full emphasis on self-ownership and negative freedom that defines market libertarian thought. Tom G. Palmer has responded to Cohen's critique.

Green politics

The green movement has been influenced by left-libertarian traditions, including anarchism, mutualism, Georgism and individualist anarchism. Peter Kropotkin provided a scientific explanation of how mutual aid is the real basis for social organization in his Mutual Aid: A Factor in Evolution. New England transcendentalism and German Romanticism, the pre-Raphaelites and other back to nature movements combined with anti-war, anti-industrialism, civil liberties and decentralization movements are all part of this tradition. In the modern period, Murray Bookchin and the Institute for Social Ecology elaborated these ideas more systematically. Bookchin was one of the main influences behind the formation of the Alliance 90/The Greens, the first green party to win seats in state and national parliaments. Modern green parties attempt to apply these ideas to a more pragmatic system of democratic governance as opposed to contemporary individualist or socialist libertarianism. The green movement, especially its more left-wing factions, is often described by political scientists as left-libertarian.
Political scientists see European political parties such as Ecolo and Groen in Belgium, Alliance 90/The Greens in Germany, or the Green Progressive Accord and GroenLinks in the Netherlands as coming out of the New Left and emphasizing spontaneous self-organisation, participatory democracy, decentralization and voluntarism, being contrasted to the bureaucratic or statist approach. Similarly, political scientist Ariadne Vromen has described the Australian Greens as having a "clear left-libertarian ideological base".
In the United States, green libertarianism is a political philosophy based upon a mixture of political third party values such as the environmentalism of the Green Party and the civil libertarianism of the Libertarian Party. Green libertarianism is a left-libertarian philosophy that attempts to consolidate liberal and progressive values with libertarianism.

Libertarian socialism

Libertarian socialism is a left-libertarian group of anti-authoritarian, anti-statist and libertarian political philosophies inside the socialist movement that rejects socialism as centralized state ownership and control of the economy and sometimes the state itself.
Libertarian socialism criticizes wage labour relationships within the workplace, instead emphasizing workers' self-management of the workplace and decentralized structures of political organization, asserting that a society based on freedom and justice can be achieved through abolishing authoritarian institutions that control certain means of production and subordinate the majority to an owning class or political and economic elite. Libertarian socialists advocate for decentralized structures based on direct democracy and federal or confederal associations such as citizens' assemblies, libertarian municipalism, trade unions and workers' councils.
All of this is generally done within a general call for libertarian and voluntary human relationships through the identification, criticism and practical dismantling of illegitimate authority in all aspects of human life. It opposes both authoritarian and vanguardist Bolshevism/Leninism and reformist Fabianism/social democracy.
Past and present political philosophies and movements commonly described as libertarian socialist include anarchism as well as Communalism, some forms of democratic socialism, eco-socialism, guild socialism, libertarian Marxist, various traditions of market socialism, several New Left schools of thought, participism, revolutionary syndicalism and some versions of utopian socialism.
Left-libertarian Noam Chomsky considers libertarian socialism to be "the proper and natural extension" of classical liberalism "into the era of advanced industrial society". Despite libertarian socialist opposition to Fabianism and modern social democracy, both have been considered as part of the libertarian left alongside other decentralist socialists.

Market-oriented left-libertarianism

Carson–Long-style left-libertarianism is rooted in 19th-century mutualism and in the work of figures such as Thomas Hodgskin, French Liberal School thinkers such as Gustave de Molinari and American individualist anarchists like Benjamin Tucker and Lysander Spooner, among others. Certain American left-wing market anarchists who come from the left-Rothbardian school such as Roderick T. Long and Sheldon Richman cite Murray Rothbard's homestead principle with approval to support worker cooperatives. While American market-oriented left-libertarians after Benjamin Tucker tended to ally with the political right, relationships between such libertarians and the New Left thrived in the 1960s, laying the groundwork for modern free-market left-libertarianism.
Austrian School economist Murray Rothbard was initially an enthusiastic partisan of the Old Right, particularly because of its general opposition to war and imperialism, but long embraced a reading of American history that emphasized the role of elite privilege in shaping legal and political institutions, one that was naturally agreeable to many on the left. In the 1960s, he came increasingly to seek alliances on the left, especially with members of the New Left, in light of the Vietnam War, the military draft and the emergence of the Black Power movement. Working with other radicals such as Karl Hess and Ronald Radosh, Rothbard argued that the consensus view of American economic history, according to which a beneficent government has used its power to counter corporate predation, is fundamentally flawed. Rather, government intervention in the economy has largely benefited established players at the expense of marginalized groups, to the detriment of both liberty and equality. Moreover, the robber baron period, hailed by the right and despised by the left as a heyday of laissez-faire, was not characterized by laissez-faire at all, but it was a time of massive state privilege accorded to capital. In tandem with his emphasis on the intimate connection between state and corporate power, he defended the seizure of corporations dependent on state largesse by workers and others whilst arguing that libertarianism is a left-wing position. By 1970, Rothbard had ultimately broke with the left, later allying with the burgeoning paleoconservative movement. He criticized the tendency of left-libertarians to appeal to "'free spirits,' to people who don't want to push other people around, and who don't want to be pushed around themselves" in contrast to "the bulk of Americans", who "might well be tight-assed conformists, who want to stamp out drugs in their vicinity, kick out people with strange dress habits, etc." while emphasizing that this was relevant as a matter of strategy. He wrote that the failure to pitch the libertarian message to Middle America might result in the loss of "the tight-assed majority". Those left-libertarians and left-wing followers of Rothbard who support private property do so under different property norms and theories, including Georgist, homestead, Lockean, mutualist, neo-Lockean and utilitarian approaches.
Some thinkers associated with market-oriented left-libertarianism, drawing on the work of Rothbard during his alliance with the left and on the thought of Karl Hess, came increasingly to identify with the left on a range of issues, including opposition to corporate oligopolies, state-corporate partnerships and war as well as an affinity for cultural liberalism. This left-libertarianism is associated with scholars such as Kevin Carson, Gary Chartier, Samuel Edward Konkin III, Roderick T. Long, Sheldon Richman, Chris Matthew Sciabarra and Brad Spangler, who stress the value of radically free markets, termed freed markets to distinguish them from the common conception which these libertarians believe to be riddled with statist and capitalist privileges. Also referred to as left-wing market anarchists, these market-oriented left-libertarian proponents of this approach strongly affirm the classical liberal ideas of self-ownership and free markets, while maintaining that, taken to their logical conclusions, these ideas support strongly anti-corporatist, anti-hierarchical, pro-labor positions in economics; anti-imperialism in foreign policy; and thoroughly liberal or radical views regarding such cultural issues as gender, sexuality and race. While adopting familiar libertarian views, including opposition to civil liberties violations, drug prohibition, gun control, imperialism, militarism and wars, left-libertarians are more likely to take more distinctively leftist stances on cultural and social issues as diverse as class, environmentalism, feminism, gender and sexuality. Members of this school typically urge the abolition of the state, arguing that vast disparities in wealth and social influence result from the use of force—especially state power—to steal and engross land and acquire and maintain special privileges. They judge that in a stateless society the kinds of privileges secured by the state will be absent and injustices perpetrated or tolerated by the state can be rectified, concluding that with state interference eliminated it will be possible to achieve "socialist ends by market means".
According to libertarian scholar Sheldon Richman, left-libertarians "favor worker solidarity vis-à-vis bosses, support poor people's squatting on government or abandoned property, and prefer that corporate privileges be repealed before the regulatory restrictions on how those privileges may be exercised". Left-libertarians see Walmart as a symbol of corporate favoritism, being "supported by highway subsidies and eminent domain", viewing "the fictive personhood of the limited-liability corporation with suspicion" and doubting that "Third World sweatshops would be the "best alternative" in the absence of government manipulation". Left-libertarians also tend to "eschew electoral politics, having little confidence in strategies that work through the government prefer to develop alternative institutions and methods of working around the state". Agorism is a market-oriented left-libertarian tendency founded by Samuel Edward Konkin III which advocates counter-economics, working in untaxable black or grey markets and boycotting as much as possible the unfree, taxed market with the intended result that private voluntary institutions emerge and outcompete statist ones.

Steiner–Vallentyne school

Contemporary left-libertarian scholars such as David Ellerman, Michael Otsuka, Hillel Steiner, Peter Vallentyne and Philippe Van Parijs root an economic egalitarianism in the classical liberal concepts of self-ownership and land appropriation, combined with geoist or physiocratic views regarding the ownership of land and natural resources.
Scholars representing this school of left-libertarianism often understand their position in contrast to right-libertarians, who maintain that there are no fair share constraints on use or appropriation that individuals have the power to appropriate unowned things by claiming them and deny any other conditions or considerations are relevant and that there is no justification for the state to redistribute resources to the needy or to overcome market failures. A number of left-libertarians of this school argue for the desirability of some state social welfare programs. Left-libertarians of the Carson–Long left-libertarianism school typically endorse the labor-based property rights that Steiner–Vallentyne left-libertarians reject, but they hold that implementing such rights would have radical rather than conservative consequences.
Left-libertarians of the Steiner–Vallentyne type hold that it is illegitimate for anyone to claim private ownership of natural resources to the detriment of others. These left-libertarians support some form of income redistribution on the grounds of a claim by each individual to be entitled to an equal share of natural resources. Unappropriated natural resources are either unowned or owned in common and private appropriation is only legitimate if everyone can appropriate an equal amount or if private appropriation is taxed to compensate those who are excluded from natural resources.
