I can generally summarize the conditions over time in the Soviet Union, although they did vary to a great degree depending on the time and the crises involved. Because this was a communist country (actually, the original one), the economy was centrally planned by the government. Where you worked, how much you produced, how much that would cost were all decisions by the central government and not the businesses themselves. You would hardly ever get a raise, but prices for gods would not rise either.
There was no freedom of speech, you had to be very careful what you said in public or you could be "denounced" by anyone else, and this would mean you could get imprisoned or even killed. That was more true in the first three decades of the republic than later.
Education was free, all the way through college. If you tested high enough and your career choice was approved, they would pay for your schooling all the way through graduate school. While there was propaganda and bias in the humanities and arts, math and science education was among the best in the world. The literacy rate skyrocketed.
It was difficult to always get the things you needed to survive on. There were constant shortages at the stores, and long lines waiting for bread, meat or soap. There might be a five year wait for an apartment or a car.
