One irony here is that the more worthless college education becomes (in the non-STEM areas at least), the more outrageously expensive it becomes, while with electronics, the use value of the gear skyrockets while prices plunge.
In the 'higher education' sector, a trifecta of corruption and stupidity. The federal government underwrites huge loans with no oversight; greedy and mostly useless administrators proliferate like rabbits, raising tuition and fees because of the availability of federal funds; stupid students go deep into debt to finance worthless degrees.
The degrees are not only economically worthless; they are intellectual junk to boot. Outside of the STEM areas, and the medical schools, the universities of the land have become leftist seminaries and hotbeds of political correctness.
