I felt pretty much the same, during my last post-doc. I had a friend who rebuilt power plant equipment. He got to work on very cool stuff, and he made very good money. I did a straight chemistry BS and basically a biochemistry PhD, so I remain largely ignorant of the humanities. But I did learn to write clearly (if not artfully) and I learned very well how to learn. In my experience, that's what's most important. Facts get dated quickly, and now they're findable online. But how to learn, that's essential. But then, this was some decades ago. My BS cost about $20K, and the PhD was "free". Indeed, "worked" as a research assistant during grad school. The salary was very low (albeit tax-free) but it was enough for rent and food.
