We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Liberal Arts, by definition having no exchangeable value, but intrinsic value (supposedly), have always been credentialing/signaling. That in the past the Liberal Arts student learned to write and speak well was a side benefit that did assist them in advancing through on-the-job training.
After years or pursuing degrees and advanced degrees and touting the same to my children (only one of whom actually went the whole hog), and then working in a university, I finally admitted that college is not for everyone, and certainly not useful to all. So far, all but one of my grandchildren have found careers without benefit of a college degree, no debilitating debt, and far better earnings than most college graduates these days can boast. It took me decades to pay off my student loans. Most of the college grads these days may never manage it.
And should your grandchildren wish to become "educated" as the professors like to sneer, surely you, and perhaps they themselves, could compile the list of works to read and forums in which to participate.

What we become depends on what we read after all of the professors have finished with us. The greatest university of all is a collection of books.

I majored in mechanical engineering, graduating from university in 1979, and went to work for Boeing in Seattle. I soon realized that I had been ready for the technical level of the work in (not after, but while in) high school. My sheepskin was no more than a credential. I left engineering work after 2-1/2 years, so can not comment on whether I would ever have used calculus, statics/dynamics, etc. later in a career in the industry.
My education did prepare me for what I do now, translating Japanese technical papers into English.
