I was lucky since: a) I was born in the 1970s rather than when Stalin was running the country; b) I was an only child of very hard working and accomplished parents - my mother ran an IT department for a global exporter and had 40 people reporting to her, and yet she had to work another job as well to make ends meet; my father worked two jobs. I was pretty sheltered, although when one reads Balzac and Shakespeare and Dickens at the age of 10 and sees how the poor in their stories lived and then compare it to your life in the USSR, well, the comparison was not in favor of the USSR.
The shops were empty - literally (no cheese, no meat, no fish, no sausages, no clothing, no books, no toilet paper). You could not really say anything anti-government, and these days the atmosphere on American campuses and large corporations with political correctness is similar. You do not get arrested in the US for saying certain things, yet, but... Crime was pretty bad - to survive most people broke laws, and it is a slippery slope from stealing from the government to stealing from other people, to robbery, murder. Corruption was insane and everywhere.
No respect for human life, we were all cannon fodder for the glories of communism. Afghan war was good example.
My grandfather was jailed for being a Latin spy - whatever that means in the early 1930s. He was lucky, he was released after seven months in jail and immediately left for the other side of the USSR.
Adults felt it much more than I did, I was twelve when I left the workers's paradise. Had I been born 50 years earlier, would have been orders of magnitude worse. Stalin's purges and orchestrated starvation in Ukraine killed tens of millions.
