The Pyramid of Capitalist System is a common name of a 1911 American cartoon caricature critical of capitalism, copied from a Russian flyer of c. 1901. The graphic focus is on stratification by social class and economic inequality. The work has been described as "famous", "well-known and widely reproduced". A number of derivative works exist.

Social stratification refers to a society's categorization of its people into groups based on socioeconomic factors like wealth, income, race, education, ethnicity, gender, occupation, social status, or derived power. It is a hierarchy within groups that ascribe them to different levels of privileges. As such, stratification is the relative social position of persons within a social group, category, geographic region, or social unit.
