If your premise is true, then the most redistributive governments would be the most civilized.

20th century communism would not provide a lot of evidence in favor of that theory.

They (the mixed economies of the West and, even within that set, those with the most redistribution and strongest social safety nets) are.

20th Century Communist regimes (Leninism and it's descendants) wasn't redistributive on an ongoing basis, it was simply a one-time transfer of effective power over the entire economy from one narrow elite to another, hence why non-Leninist Marxists often referred to it as “state capitalism”.

No, I did not say how much, it is like anything, not too little, not too much.

Communism is way way too much, and ignores fundamental aspects of humanity.
