There's also the question of the nomenklatura and the army. It cannot be denied they enjoyed privileges
Oh it cannot be denied? There must be some pretty strong numeric data suggesting that. Care to share?
Western liberal democracies [...] preserve more individual freedoms than leninist states do
Ask that to Vietnamese, Iraqi, Libyans, Venezuelans, Cubans, Burkinabe, Algerians... Turns out that the western liberal democracies don't preserve individual freedoms, they only export more of the authoritarianism abroad and keep the situation easier at home because the richer working class is less prone to murdering them!
It's good the Soviet Union after Stalin tried to improve the standard of living
After? With Stalin, life expectancy went from 28 to 55 years of age, land collectivization was successfully carried out (not without difficulties), and massive literacy campaigns taught everyone to read. Again, not because of Stalin in particular, because history isn't made by one person and he wasn't an absolute dictator the way you believe he was.
You've completely ignored my point of how it is possible that the USSR got 5 benevolent dictators in a row maintaining the highest welfare state and lowest inequality in the history of the region.
Oh yeah, "real communists" were killed by the evil tankies that established the highest welfare state and lowest inequality in the history of the region.
Tell me, if it's tankies killing the real communists, where are all of these real communists who build housing in the rest of the world? Spain, France, USA, Brazil, Indonesia? Any there? Also killed by le evil tankies?
