Why doesn't Communism (Marxism,Trotskyism etc) work?

The failure of Marxism is its failure to perfect human nature according to its definition. That is why it starts out as a totalitarian bureaucracy and get steadily more brutal and oppressive as time goes on. Look at the case of the Kronstadt sailors.

They were the Balshevic elite force during the revolutionary war against the whites. After they returned to Petrograd and asked for their democratic rights, Lenin sent the Red army and slaughtered all of them. As Rosa Luxemberg said, "It is not so much the dictatorship of the proletariat as dictatorship over the proetariat" Marxist economics is simply unworkable, both Russia and China gave it up after millions had starved to death, and then implimented a state controlled capitalist system.
