I had a copy of "Differential and Integral Calculus" by Piskunov that belonged to my father. The prologue said it was used in the curricula of technical schools in the USSR. I used to think about that fact a lot and tried to imagine what those Soviet technical schools would be like. There was a lot of content there that I did not see in any of the seven math courses we had at uni.
One of my teachers said the only job for her was factory book keeper in some nasty factory. She came over to the US in the 90s and became a CPA then taught college level accounting.
She said a lot of people she immigrated with were overqualified for the jobs in Russia (factory book keeper or technician with PhD level knowledge). The same applied to the US but there were many more options than factory jobs. Her husband was on the technical track and found a job as a professor somewhere.
