Grandparent said "communist", not socialist, so while many people argue about the difference it doesn't seem relevant here.

Revolutionary Spain did not survive long enough to discuss IMO.

Cuba... egalitarian in what way? Is there anything the government does that the citizens can legally undo without overthrowing it? (Note that a benevolent dictatorship can exist, in theory, and among other things it can be a communist - or a racist - dictatorship; nothing prevents from the dictator to grant freedoms to the subjects, the point is that nothing prevents him from taking them away, either. If you don't refer to rights in the sense of things the government cannot prevent you from doing but instead refer to "egalitarian" in some sense of Cuban citizens living substantially different lives than Soviet citizens, I'd be curious to hear what exactly you mean.)
