Unified society...everyone does their part...shared work...equal class system
It's a society where you either conform, or you're forced to move/arrested.
If you don't want to "help" people the way society demands, you're screwed. If you believe a system is flawed and you want nothing to do with it, you're forced to partake and support it.
Communists often talk about communism being true democracy. Democracy is mob rule. But, when the majority wants what is best, is that not a good thing? Even majorities can be wrong, and democracy becomes quite an issue when you're talking about 60 or 70 percent popular opinion forcing the rest to live a particular way.
I always wondered what would happen in a truly democratic, anarchist, and communist, nation where people preferred free trade.
