In my country, except janitors and people working cafeteria, pretty much any job in healthcare requires some kind of degree (exception is taking care of old folks in private homes, but even those require a substancial amount of staff with some kind of schooling in it)

I never claimed they were? I said that when a job is automated away, any that replace it inevitably require a higher skill level. Thus the skill floor rises over time.

That's the key. That's a specific task that we can't (yet) automate.
