I don't think countries that are ruled with communism ended up as a dictatorship because of the ruling class. Maybe it was inevitable.

What makes me say that? Because the concept of complex systems (https://en.wikipedia.org/wiki/Complex_system) gave me a new approach to think about different economic and social organizations.

Economy (and society) is a complex system and it is impossible to model perfectly (at least for now). So any approach that attempts to have everything under control will (eventually) fail. Or you may need to use force to mold the reality to your hypothetical system.

Capitalism may not be the best system there is, but it certainly aligns with a complex systems point of view.
