Salaries probably pay factor as well? Check the sunshine list, plenty of radiologists making 600k/year. That's literally 10x of the median salary.

Also is that too high? I know a guy in his early 40s still finishing his 2nd radiology fellowship (4 years undergrad, 4 years med school, 5 years radiology, 1-2 years each fellowship = cost of his 20s/30s) to get a job...
I find HN comments on healthcare compensation when it comes up funny because on the other hand compensation expectations in the tech gold mine here are justified. E.g. I take home less in CDN dollars than an L3 SE at google without benefits. I'm happy with what I do/get but there is a mismatch in rationalizing high compensation, markedly more years of university and training, and from my point providing a societal benefit.
