A white elephant is a possession which its owner cannot dispose of and whose cost, particularly that of maintenance, is out of proportion to its usefulness. In modern usage, it is an object, building project, scheme, business venture, facility, etc., considered expensive but without use or value.
Background
The term derives from the sacred white elephants kept by Southeast Asian monarchs in Burma, Thailand, Laos and Cambodia. To possess a white elephant was regarded as a sign that the monarch reigned with justice and power, and that the kingdom was blessed with peace and prosperity. The opulence expected of anyone who owned a beast of such stature was great. Monarchs often exemplified their possession of white elephants in their formal titles. Because the animals were considered sacred and laws protected them from labor, receiving a gift of a white elephant from a monarch was simultaneously a blessing and a curse. It was a blessing because the animal was sacred and a sign of the monarch's favour, and a curse because the recipient now had an expensive-to-maintain animal he could not give away and could not put to much practical use. In the West, the term "white elephant" relating to an expensive burden that fails to meet expectations, was first used in the 1600s and became widespread in the 1800s. According to one source it was popularized following P. T. Barnum's experience with an elephant named Toung Taloung that he billed as the "Sacred White Elephant of Burma". After much effort and great expense, Barnum finally acquired the animal from the King of Siam only to discover that his "white elephant" was actually dirty grey in color with a few pink spots. The expressions "white elephant" and "gift of a white elephant" came into common use in the middle of the nineteenth century. The phrase was attached to "white elephant swaps" and "white elephant sales" in the early twentieth century. Many church bazaars held “white elephant sales” where donors could unload unwantedbric-à-brac, generating profit from the phenomenon that "one man’s trash is another man’s treasure" and the term has continued to be used in this context. In modern usage, the term now often refers in addition to an extremely expensive building project that fails to deliver on its function or becomes very costly to maintain. Examples include prestigious but uneconomic infrastructure projects such as airports, dams, bridges, shopping malls and football stadiums built for the FIFA World Cup. The term has also been applied to outdated or underperforming military projects like the U.S. Navy's Alaska-class cruiser. In Austria, the term "white elephant" means workers who have little or no use, but are not terminable.
