Communism and fascism differ in their economic, political, and social structures. Communism advocates for common ownership and production based on need, with no social classes or private property. It aims for change through government action. Fascism glorifies the state and embraces a strict social hierarchy led by a single authoritarian leader. It permits some private property and business ownership but under heavy state control and direction. Both ideologies have been used to justify discrimination, though communism aims for equality while fascism believes in racial supremacy.
