I think your view is a tad optimistic. Many people had difficult lives just because they didn’t want to be members of the party. Thier kids didn’t get to good schools, or got to the one 30 minutes by train, they lost jobs and were forced to dry laundry with engineering degrees.
There was even a joke about this:
⸻
In Poland, during the times of hard socialism, a math associate professor calculated that a shipyard worker earned three times more than he did. So he thought “screw this,” crossed out the titles before and after his name, and went to work in a factory.
Of course, he was doing well in the factory — he didn’t strain himself too much and earned three times more than at the school. Then the factory introduced an evening school for workers, with the promise that whoever attended would get a raise. So the associate professor signed up and started going.
On the very first lesson — bam — mathematics. The level was like the first year of high school, so the associate professor was just dozing off, not paying attention. The teacher noticed him, called him up to the board, and asked him to calculate the area of a circle.
The professor started writing, but for the life of him couldn’t remember the formula for the area of a circle. So he decided to derive it. He wrote the conversion to polar coordinates, then integrated it, and ended up with –πr². So he stood there, wondering where the minus sign had come from.
And from the back row, someone whispered:
“Reverse the integration interval.”
