Hmm... did I say they were underpaid?
> How many people do you know who only have a high school diploma?
My parents, all my grandparents, most of my aunts and uncles, most of my cousins. I would say "me", but that would be a lie, because I don't even have a high school diploma. Not sure about friends and acquaintances. Most of them are tech workers, so formal education rarely comes up.
> Who have no other options that pay more than $60k/year?
Lots of the people I mention, including myself, make or have in the past made more than $60k/year (at least inflation-adjusted).
Pieces of paper from a broken educational system are not determinant of how much someone can or should make.
