I double-majored in Philosophy and the History of Math and Science (to be fair, I wasn't given a choice, everything was mandatory). Those majors have basically zero practical *fiduciary* application outside of teaching, but they enriched my life beyond any measure I can come up with.
It amuses me to no end that the people who cry the loudest about education being "practical" are the same people who imagine that they venerate the Founding Fathers, the American Experiment, etc. Lulz. Jefferson, Washington, Madison, Monroe? All of them were basically Liberal Arts Majors, in the modern parlance. They studied the Trivium and the Quadrivium. They studied subjects which were intended to make them intelligent, informed Citizens, capable of making (or dismantling) a cogent argument for (or against) any thesis.
A democratic Republic rises (or falls) on the ability of the people who constitute it being able to make rational, logical assessment of the obligations of a Citizen to their fellow Citizens, as well as the reciprocal. We are seeing the extrapolated end result of your worker-bee education plan play out in real time, as people with PhDs are encouraging people to imbibe horse-dewormers in order to counteract a VIRUS. Of course their doctorates are in bridge-building, but no matter, they're DOCTORS, just like the guy in the white coat!
An education in rigorous, analytical, non-vocational thought ought to be mandatory, imho. In any case, though, what it certainly isn't is laughable or silly. We are being forced to bear witness to the evidence as I type.
