One might also argue that the real thing didn't happen yet though. Just because a lot of people attach a label to themselves and then other people come and use that label to do PR against them doesn't mean it was correct in the first place.

That said, I also don't believe in it. From what I'm seeing around me, people usually grab small short term advantages over other people even if they suffer long term consequences together after the "success". Also people really love to give power over themselves to other people. Until these two misconceptions are overcome there can't be any real attempt at communism.
