My guess is, although this is an empirical matter not one that can be settled by argument, that until the problem of power is resolved there is little hope of resolving the problem of economics.
Speaking of personal experience, I am much more resentful of having a manager telling me what to do at work than the fact I'm poorly paid. I'd suggest that "Office Space" is of a great deal more sociological significance than Das Kapital.
*Actually the Soviet Union and its satellites were (and Belarus, Cuba and probably North Korea remain) massively egalitarian economically compared to their Western counterparts. It is also true that the USSR was relatively benign as an imperial power compared to the US-Western Europe. However these facts should not suggest that the Soviet, essentially Platonic, model provide an inspiration (in terms of political structure) to Western leftists.
