I agree with aspects of what you mean. But there are exceptions on both sides.

Ofc people dont want to become human fax machines (Morse decoders) nowadays, it would feel absurd.

But also if a role allows someone to feel satisfaction in accomplishment and in being an active member of a society it can be meaningful. For example tidying up streets/yards in low income neighborhoods can make the place look much better and you can feel like you're serving folks who are in need.

It's still 10s of millions of people who could be given a job (and some hope and purpose too btw)

Edit: btw I agree there's more to life than work. But when you're unemployed and hoping for work, competing against robots and LLMs is quite crushing.

"No one wants" usually includes an insufficient wage, sometimes also an issue of insufficient investment in training for skilled folks. eg if you need a doctor in 12 years you have to start more or less today.

A quick google suggests ~18% of their working age people do not have jobs, which naturally could be shifted by incentives like money or training.

(Edit, because people are confused, I'm not talking about unemployment rate, i'm talking about labor non-participation rate as a measure of people who could be enticed into the workforce with a living wage)
