Thorstein Veblen (1857-1929) was an American economist and sociologist. His most famous work, The Theory of the Leisure Class: An Economic Study of Institutions (1899), is a treatise on economics and a social critique of consumption and of consumerism, based on the social stratification of people and the division of labor.

This work is in the tradition of Adam Smith’s Wealth of Nations and is rightly considered a classic of economic theory and social history.
