Baloney. SOCIALIST systems have done that, but not Communist "systems." Why, you ask? Because according to Marx' notion of the five stages, communism, on any large scale at all, has never happened in the history of the world. Communism is, therefore, really a theoretical concept and has never been realized.
So, when people say that Marx is wrong, no no, sir! Marx was dead on right because he cautioned that socialism would be as destructive as capitalism, until full communism is realized, which never happened.
