> on a surprisingly small salary

But if we take "surprisingly small salary" to literally mean salary, most (... all?) salaried jobs require you to work full time, 40 hours a week. Unless we consider cushy remote tech jobs, but those are an odd case and likely to go away if we assume AI is taking over there.

Part time / hourly work is largely less skilled and much lower paid, and you'll want to take all the hours you can get to be able to afford outright necessities like rent. (Unless you're considering rent as consumption/luxury, which is fair)

It does seem like there's a gap in terms of skilled/highly paid but hourly/part time work.

(Not disagreeing with the rest of your post though)
