Final answer:
In theory, communism promotes common ownership of all property, means of production, and materials. However, the actual practice of communism differs from the theory.
Step-by-step explanation:
In theory, communism promotes common ownership of all property, means of production, and materials. This means that the government, or states, should own the property, farms, manufacturing, and businesses. By controlling these aspects of the economy, Communist governments can prevent the exploitation of workers while creating an equal society. Extreme inequality of income is prevented by instituting wage controls or by abandoning currency altogether.
However, the actual practice of communism differs from the theory. The theory assumes that the move to communism is supported and led by the proletariat, or the workers and citizens of a country. Human rights violations by governments of actual Communist countries make it appear the movement has been driven not by the people, but by leadership.
