The same lies are told about capitalism as well. Capitalism has also been pretty much universally disastrous for the people forced to live under it. That's why communism (and, albeit less directly, facism) was created. Had it not been for the appalling mass suffering caused by capitalism, communism would never have been anything more than a bizarre fringe idea from a few weirdoes.
I can't stress that enough - the rise of communism is a direct result of the immense suffering inflicted by capitalism. That's a simple matter of recent (late 19th century) historical record, well documented.
Capitalism is a very ugly idea with very ugly results. Communism is a pretty idea with extremely ugly results. In practice, the least bad system anyone has come up with is heavily regulated capitalism. Capitalism is like nuclear fission in that respect - extremely useful if carefully controlled, devastatingly destructive if not.
I don't claim that capitalism is perfect (although I do accept I may have done years ago), but to be the least worst system we have, it doesn't have to be. I also prefer carefully regulated to heavily regulated, because it's very possible to have regulation that makes it worse than the unregulated position.
No better alternative can exist while resources are finite.
