Idk, as a socialist I look at it as a broadly genuine effort to create socialism that came before its time in a fairly unfavorable place which then failed precisely because the conditions weren’t really favorable.
It merits study, I don’t hate everything I see from the USSR (free healthcare, free higher education, heavily subsidized rents, and a policy of full employment don’t all seem like bad things) but more look to it as a historical example and less as a model.
In some ways I think it could be compared to the French revolution – it’s not that the French Revolution and its collapse into Bonapartism proved that abolishing feudalism and establishing a freer social order was fundamentally impossible, it just proved that the conditions weren’t in place in France in the 1790’s.
