Classical Marxism argues that society is based on conflict between social classes due to unequal distribution of wealth and power. Marx predicted that capitalism would become increasingly polarized and unstable, ultimately leading to revolution and socialism. However, Marx's predictions have not come true, and his two-class model is too simplistic. Later theorists like Gramsci and Althusser developed Marxism further, emphasizing the role of ideology and introducing concepts like hegemony and ideological state apparatuses to better explain how ruling classes maintain power. While criticisms remain, Marxist perspectives continue to provide insights into social inequalities and conflicts rooted in class divisions.
