I disagree. Socialism is not far enough for most communists.
You might even say that socialism is just a "kind word" for we are just taking our time converting you all to communism (govern-cement type)
Communism cannot work in anything larger than a tribe. Everyone must know what everyone else is contributing. And must be able to discuss balancing when necessary WITH EVERYONE ELSE.
The utopia of communism is actually anarchy where everyone cares about everyone else. A much higher morality than we can currently support. Most of humanity is about level 2 or 3. And we need to get to 7 or 8.
