Communism doesn't work but liberalism didn't work either and we've had 50 years of it having unchallenged rule. Just this little bit more destruction is what's needed for people to snap out of it? You think so? Detroit, Newark, South Africa, Rhodesia not enough?
Obviously; but only since the late 60s has it had totally unchallenged rule in the US. Before that there were still vestiges of older, evolved systems.
