I will address some of your concerns.

Karl Marx was European. His publisher was European. His early adopters were Europeans. The evidence that Europe cannot be communist is not there. Soviet Union is a pinnacle of socialist achievement. It is possible that your communism will have mass starvation and hoe strikes breaking skulls phase which is not followed by space exploration and nuclear power phase.

You are miserable now, let's asusme. People were miserable under socialism (not all of them, but the vibe was off). We can't rule out you will be happy under socialism, but no facts support that even indirectly. It will require a leap of faith.

P.S. I was replying to much longer, non-tautological and less-borderline-racist version of your comment.
