Why?
Because generations of Americans associated a college education with social upward mobility.
Unfortunately (as if often the case) the cause and effect got confused.
I.e., people who went to Harvard didn’t necessarily become rich by being at Harvard, their family was already well placed socially.
Secondly, public education became one of the principal tools for social engineering, e.g., addressing racism. A good sentiment but had an unfortunate side effect of degrading those jobs that didn’t require lots of formal education.
