Wow. Wrote a bunch and this thing timed out. Okay, a second try. This time I'll copy in case it happens again.
My qualification is that I'm married to a Russian and have been around this culture for almost 17 years now.
There is prejudice. Nothing officially existed. Nothing officially bad ever existed. (For instance, there were no laws against prostitutes because no prostitutes existed in communist paradise) But my husband and especially my mother in law are very likely to point out racial characteristics. Lots of the prejudice was directed at the provinces. Moscow was a bit of a snooty town. People often disdained anyone from the southern provinces like Georgia and Chechnya. That is not a new development.
Resources and manufacturing were purposefully kept apart, so that the provinces had to rely on the rest of the USSR for success. So steel might be made in one province, the chassis in another, and the body of the car in yet another and it would be put together in a different place altogether.
Apartments were genrally small, about 800 square feet. One, maybe two bedrooms. Lots of couch or wall beds. They were very good at economizing space.
By law, women were equal to men, except they didn't have to do the required two years in the military that the men had to do. They had the same opportunities in education and career. They had the same pay. Daycares were fantastic (By funding terms. Pretty authoritarian, but that is part of the culture), after school programs were wonderful, and the children went to summer camps for free.
However, abuse was common and accepted. My mother in law actually divorced her husband (in late 60s) because she wouldn't put up with the abuse, and her mother disowned her for two years. Divorce was very, very taboo. A woman was expected to live with it. This had not improved, but seems to have gotten worse.
Because of this workers equality, the economy was built for a two income family. Most people only had one child, but my MIL was the single mom now of two boys. Money was very tight for them.
To compound the problem, teachers required bribes. One year, the teacher took my husband aside, informed him he had an F for the year, and wrote it down in his grade book.
This kind of corruption, and forms both milder and more severe, ran top to bottom. My MIL had her boys go into cooking school, because then they could bring home food and produce. It was not an official perk, but everyone did things like that. And the higher up, the worse this practice was. In fact, the corruption of the government structure (and in the Soviet Union every industry was part of the government structure) is the foundation of the Russian mafia of today.
They did have fashion, though. The 60s were more posperous than the 70s. The corruption was really bad by the 70s.
No Christmas was allowed, but New Years celebrations annexed the Christmas traditions.
Anyway, if you have any questions or want more details just ask.
Hope this helps.
