Thanks for posting OP. The article states that only a minor percentage pay over $70,000 and that includes undergraduate.
However, about half of the PhDs earned by blacks are in education and they may (or may not) have a higher than normal debt load. I don't know how tight the job market is for them. I assume PhDs in education would be just as happy to work for schools as a university.
A large percentage of STEM PhDs are earned by foreigners.

Unfortunately our debt load is higher (why are we always drawing the short straw)? See above chart from Department of Ed. URM means Under-represented minority and SBE is social, behavioral, and economic sciences (as opposed to STEM).
