I cringe any time someone points to a failure in an unimaginably different circumstance as evidence for why something won't work here.
Some people get bit by a dog and are afraid of dogs their whole lives. It's irrational.
Also, socialism and communism are not synonyms.
Doesn't it seem ingenuine how everything good is socialism and everything bad is communism? Also if socialism can't compete with capitalism then it's doomed. Socialism must make capitalism illegal in order to succeed and I don't want to be in a place where capitalism is illegal. And "market socialism" is not socialism either.
