This probably says a lot more about the lack of upward mobility in the struggling french economy than anything else. Youth unemployment at a staggering 26% and almost no economic growth in the past few quarters.

In more vibrant economies these jobs are seen as largely unattractive and often as a stepping stone to becoming a nurse's aid, nurse, doctor, etc.

One of the major imported jobs in even closed societies like Japan is senior caregivers. Its hard and ugly work, and often thankless (how can a senior with dementia appreciate you?). Migrating to different jobs or eventual burn out is a real issue in this industry.

Counterexample: Switzerland, where it is also the same few people (my mother has daily caregivers), and the economy is doing fine.

Well, Sweden definitely is not hitting that mark.
