Stalin died less than a decade after the soviets' incredible victory against the nazis, which made him loved by a ton of people. And then the party decided to undo everything he did? You could debate whether stalin was good or bad, but my question is what made the party switch directions after stalin died?
Because party functionaries controlled the levers of power without significant material benefit and without strong feedback mechanism (outside of purges). This disbalance couldn’t continue. So naturally that led them to assuming the previous ruling class aesthetics, and then ideology.
