But there is another, countervailing aspect. People think they have no alternative if they live in a society that provides no upward mobility.
I happen to live in a country (the US) that provides the greatest degree of upward mobility in the world, which is why immigrants from every other country come here. But there are people here who, out of a form of sanctimony disguised as "empathy", want to insist to people in service jobs that they are permanently stuck there and should view themselves as members of a oppressed class, rather than emphasizing (let alone providing) the opportunities for people to reach their highest potential.
We're not the UK, let alone Russia. I was a taxi driver. Numerous former bartenders I know own houses and work in tech. Friends who were barely employable ten years ago are now master carpenters, mechanics, or truck drivers with several trucks. And some are "professional", if you consider coding professional. I think it's more like plumbing without a license.
My point is that pity and putting people in a box with hoity-toity empathy and little handouts is degrading and belittling, and saying they have to have those jobs forever is essentially a backhanded way for people to seem empathetic but actually guarantee that the existing hierarchy remains.
