Conflict theory

Conflict theorists take the opposite view, and posit that individuals and social groups or social classes within society interact on the basis of conflict rather than agreement. One prominent conflict theorist is Karl Marx who conceived of society as operating on an economic "base" with a "superstructure" of government, family, religion and culture. Marx argues that the economic base determines the superstructure, and that throughout history, societal change has been driven by conflict between laborers and those who own the means of production.
