"True Communism" has always been the promise of heaven-on-earth without a God. It never happens, of course--any power vacuum is immediately filled by greedy people with no scruples. At least in a society with a God, there's something for the power-brokers to be afraid of.
Autocrats are pervasive and sometimes they feel inevitable, which is why it's nice when we are able to build social structures that are resistant to corruption.
Unfortunately even they are fallible.
But why did you say this in response to my comment?
