I'm from a country that's been under Communist regime (Poland) from late 40s to late 80s and it wasn't pretty. Just see any history book. They shoot up multiple workers for striking against the government, because there wasn't enough bread or food or any luxuries for anyone. People kept looking with jealousy at Western Countries. Hell, even Holodomor (the great hunger of Ukraine) or the great famine in China or the situation in North Korea was caused by communism.
I think it's good in theory, but I don't think it's going to work. Especially if to even make it's existence you need a society that has reached late-stage capitalism. Capitalism is also flawed, but it worked on a large scale sort of nicely for quite some time and the issues the west is currently facing aren't necessarily caused by this.
Anyone care to explain?
