Eduction also allows for the construction of more sophisticated filters to protect beliefs in the ideological, unfortunately.
Education Plus Ideology Exaggerates Rejection of Reality
As for the topic at hand I believe the Hatch Act prevents me from stating my opinion.
This brings to mind some threads I've seen on AT. A recent one is what you would gift your children with- great wealth, health, or wisdom. The people who thought you could buy wisdom or that wisdom is the same as knowledge was depressingly high. Some of the most educated people I know are among the most foolish. Most of those have a great knowledge of one or a few things, but a broad exposure with some depth? I hardly know anyone like that these days. Higher education is merely a means to a financial end, with a productive specialist having monetary value being the end result, but being a "smaller" person as well. Because of circumstance and inclination I had extraordinary education encompassing engineering, biology, health care, scientific research, and the associated exposure to physics, chemistry, and on and on. I also took electives which were not of a technical nature whenever possible, and it was very much a liberal arts focus on history, art, literature. Photography was extremely helpful as it taught me how to see.
The end result for those who are so inclined is a facility to draw from a broad background and make connections that others cannot possibly do.
Granted my circumstances were fortuitous and unusual, but our emphasis on a narrow focus for employment being the only worthwhile thing in education prevents others from appreciating a larger world and the pleasure that an enhanced perspective brings. It also brings dangerous intellectual tools to the ignorant, despite their degrees, as you noted. Not everyone can be as lucky as I was although at the time I didn't view the circumstances as such, but the utter disregard and occasional loathing of going beyond a narrow focus is something I view as a distressing trend.
