Means of labor
Means of labor is a concept in Marxist political economy that refers to "all those things with the aid of which man acts upon the subject of his labor, and transforms it." Means of labor include tools and machinery, as well as buildings and land used for production purposes and infrastructure like roads and communications networks and so forth. Labor, Itself defines "work, especially hard physical work."
The means of labor are one of three basic factors of the production process, along with human labor, and the subject of labor.
In some formulations, the means of labor and human labor comprise the productive forces of society, other formulations define productive forces more narrowly as the union of instruments of production and the workers who wield them.
