I don't think that's the key feature of Communism but it sure sounds nice. The way you know that's not the key feature or perhaps philosophical underpinning is because if that were true you could just start your own Communist firm, collective, "facility that generates profits" today under democracy and free markets.

I hear you on the potential for state nationalization of companies to turn into fascism, though. It's often hard to tell the difference between some of these authoritarian regimes (fascism, dictatorship, communism) because they tend to take similar actions from time to time albeit with different goals.
