Communism is the pursuit of freedom and equality by the elimination of private property.
Capitalism is the pursuit of freedom and equality by making private property available to everyone.
Neither strategy is possible because of Human Nature.
The path to Communism passes through Socialism. Socialism, defined as a system of society by which the means of production is controlled by the state, centralizes power to a single all-powerful institution. The last step to achieve Communism is for that central institution, the state, to sacrifice its power. Given Human Nature, that last step is impossible.
The path to Capitalism passes through Industrialism. Industrialism, defined as a social structure that is dominated by large industries, centralizes power into a few industries. The last step to achieve Capitalism is for those few industries to sacrifice themselves. Given Human Nature, that last step is equally impossible.
Capitalism and Communism are both religions, as they can only be pursued through the effort to control human behavior.
Capitalism and Communism are two paths to the same place.
