The document defines social class according to Weber as groups ranked by wealth, power, and prestige. It discusses trends in wealth distribution in the US becoming more unequal since the 1970s. Power elite refers to those controlling business, government, and military. Prestige is linked to occupational status and rankings. Status inconsistency means ranking higher on some dimensions than others. Sociological models of social class include Wright's four class model and Kahl and Gilbert's six class model. Social class affects many life outcomes and experiences like health, education, politics, and contact with the criminal justice system.
