I feel like an assumption I come up against a lot with liberals is that the USSR had basically the same ownership class structure and wealth distribution that similarly developed capitalist classes had. I tried Binging this but don't have a good sense of what authors to trust.
The Death of Stalin gets a lot wrong (whatever, it's not supposed to be a documentary, it's funny), but it's great that they accurately show Khrushchev and Molotov living in these incredibly modest apartment flats in Moscow.
even that dacha stalin was living in is a fucking joke compared to the white house (which itself is modest compared to european state residences)
