Real communism was tried and worked – in communities under 100-200 people (like kibutzim). This feeling of community, where people truly care about one another, is detrimental for communism to work – and turns out, millions of people can be shaped into something similar only under a terror and propaganda machine.

Free people will never care about millions of their "comrades" the same way the can care about their 100-200 closest social connections.
