I’m sorry, but this is ridiculous. Only PhD programs in the sciences are reliably funded. That doesn’t mean that ALL of the other graduate programs are “not worth” going to and that graduates of all of them are doomed to live lives of eternal servitude as adjuncts. There are other law schools worth going to out of the 3 you mention.
And there are other professional graduate programs besides med school and b-school and law school. Sheesh.
What an incredibly narrow view.
