Didn’t Thomas Sowell cover this problem decades ago?
Yep.
He did. The problem is that colleges and programs have reduced standards in an effort to reduce the mismatch. Virtually every discipline outside of STEM has been destroyed, and the libtards are working hard to lower STEM standards. Professional schools such as medical and law schools? What a joke. Unfortunately, most students in college don’t belong there, which is why perhaps a majority don’t graduate and so many take “bogus studies” majors. On th eother hand, the unqualified students do provide a massive amount of cashflow to the colleges, which supports a massive and parasitic administrative apparatus.
