You can contrast it with the sciences

There's a joke that grad school and med school are polar opposites - med school is hard to get into and easy to get out of, while a PhD is easy to start and hard to finish

Being a postdoc sucks, and you have to be pretty willing to do something radically different than what you did as a student - but it isn't the end of the world.

I can't see a situation where it makes health in the US worse overall to increase the number of students.
