A) Well, it's you vs. the Pope and I!
B) Fine, drop communism altogether -- it's evil and disgusting and bit my finger and should never be tried again. Can we work on a society where the means of production are owned by groups of laborers?
A lot of the world is a free-market and labors can absolutely own the means of production. Is there some government regulation in particular that you think is preventing this?
Re: B my guess is probably not (human nature and all that), but I'm open to ideas! I just think failed experiments where tens of millions died are probably not ones where we just flippantly "try again".
