alt Hacker NewsThat's why I stated that the marginal job is what sets the reward. We actually have a lot more people wanting to do these jobs than we reasonably have a use for.

What on earth are you talking about? In the US (which seems to be the context in question), Actual Registered Nurses™ are not by any means "scarce" and in fact make up the clear majority of all nurses. Nor do they get "paid a lot" compared to the demands of their jobs, especially considering this is a country that throws the same salaries at people for the mighty skill of writing JavaScript for a SaaS.
