Why did communism always turn into a kind of dictatorship?
Afaik this happened with every single instance of a communist country. Communism seems like a pretty good idea on the surface, but then why does it always become autocratic?
Because of bad ideology. States, classes, inequalities, and hierarchies are good and desirable. Try to build a system ignorant of the primary components and then wonder why it always fails.
Chiapas doesn't seem to be failing. Going on 30 years now. Rojava isn't failing either, due to it's system, but rather being attacked on the regular by imperialist nations like Russia and the US.
