Socialism is a ISM. This ISM doesn't kill anyone, just as guns by themselves don't kill people. Your thesis is like what the left uses on gun control.

What do you call farmer co-ops? The problem is despots can more easily get into power and take control of ANY ISM and recreate society. Totalitarianism or authoritarianism ensues. Communism is what kileld millions of people, socialism can lead into communism if you let despots take over.

Just remember that Capitalism isn't as different as you think to communism. At least not crony-capitalism of what we have today. The USSR would not be where it was or would have grown so powerful if it were not for capitalist giving them billions in arms and ammunition and technology.
