This document outlines the key differences between capitalism, socialism, and communism. Capitalism is based on private ownership and laissez-faire markets, while communism believes in collective ownership and a planned economy with no private property. Socialism is presented as a transition stage between capitalism and communism, where workers take control of the country and its resources. The document then describes Marx's five stages of societal evolution from primitive communism to advanced communism, where boundaries cease and all work to benefit each other.
