In general, I agree about the need for more professional training, not just in "business," of which there are already far too many degree programs. We need a lot more schools that teach the skilled trades at the high school level. Pushing it all to post-secondary education is a scam-- the public are asked to pay twice over for an education that ought to have been completed in high school.
There's also the point that certain subjects like political philosophy and history are necessary to understand the Constitution and be an informed citizen, while others (to state it simply) are concerned with the good, the true, and the beautiful, and so are worth studying for their own sake. There are hardly any colleges or universities left that teach the humanities the way they should.
As a matter of fact, New Testament describes great the middle class life around 30AD. Jesus and all his apostles were solid middle class. No slaves, or magnates. Slaves and magnates are mentioned, but main focus was middle class. The parable of workers in vineyard shows poor, but free workers! The owner did not get to market to buy or rent slaves, he hired freemen to work hard in the vineyard!
To make your point:
Princeton just dropped Greek and Latin as requirements for classics degree

Probably replaced by critical race theory.
Way to go Princeton!
