Doesn't really matter. Doctors spend a huge amount of time in education. There's a massive opportunity cost, and they want to be paid.

"If I'm going to study into my 30s I want a huge bag."

Understandable, though not necessarily defensible.

So it doesn't really matter because other occupations also have the same opportunity cost and want to be paid and are not getting top of the field salaries straight out of university but have to take shitty internships and maybe get decent pay past 30yo.

If people in those fields could use laws to limit competition, they would do so as well.
