Communism has some good points to it that look good on paper but are hard to put into actual practice. In theory, it would provide complete equality and democracy. Any government system can work in theory with good leaders. The Soviet Union, communism's poster-boy was cursed with a dictator who put Hitler to shame. In the Soviet Union the Communist party was the dictator. All in all Humans aren't cut out for Communism. Some species like Ants use it to great effect, but Humans are too individually centered.
