Socialism vs. Communism vs. Fascism

People seem to be throwing out these terms as though they are the same thing, but they are not.

Socialism is economic. It believes that the means of making, moving, and trading wealth should be owned or controlled by the government as a whole. In Marxist theory, socialism is the stage following capitalism in the transition of a society to communism.

Communism is economic and one party government. Communism recognizes no religion.
Fascism is economic and government. Fascism is a form of authoritarian characterized by dictatorial power, forcible suppression of opposition, and strong regimentation of society and of the economy. Fascists are against democracy.

None of the three offers more for doing more, so doing the minimum is the result. With all three there is no incentive to do better.
Socialism - from each according to his ability to each according to his contribution.

Communism - from each according to his ability to each according to his need.
Socialism and communism are founded on the idea of collective cooperation, but differ in that communists believe that cooperation should be run by a government made up of one political party (the elite that socialists decry).

Historically, fascist governments tend to be militaristic, and racist. Hitler was a fascist. Many scholars say fascism has historically attacked communism, parliamentary liberalism, and conservatism.
