Just worthy of note, Communism is not intrinsically bad, nor is capitalism (actually, the man who wrote the book on capitalism said it was f**ked up) but again... It's not intrinsically bad. "Every time it's been used it fails" because of authoritarian regimes. Such as monarchies, aristocracies, that kind of thing where they put one guy in charge of it all.
Thought I'd throw that out there so we aren't seeing it as only one thing which it is not.
