Social orientation of USSR is definitely exaggerated. In fact is was often dummy. Yeap, you could get a flat from the state for free, waiting only 10-15 years, but only if your initial accommodation was really crazy. 19 sq m room for 3 persons was considered good enough, not needing any enlargement.Stability in poverty can not be a dream. And, of course, soviet people had a lot of stress every day. Any purchase - foods, books, shoes, train tickets (in summer), etc. was a real quest, needing a lot of efforts to get acceptable goods and acceptable lives.I think the reason is because Communism was not succeeded by a balanced, well regulated model of Capitalism, but by the wild variety, with massive inequality, widespread poverty with no social state to soften the edges, and corruption. For many, this resulted in a life much worse than the one under Communism. They were poor and unfree then, but healthcare, education, employment, a roof over their head, all the basic material needs were guaranteed by the state, in contrast to what followed afterwards.
I've met several immigrants from ex-Communist countries, when I asked an elder Ukrainian lady to compare then and now, she told me that what she missed the most from Communism was the lack of stress; if someone refrained from stepping on the regime's toes, life was quiet and without much to lose sleep over.
