@chai2,
I agree with a lot of what you are saying, with some qualms.
I had this love of medicine when I was an early teen. My father had to leave med school in 1926 to take care of his mother, and went south to LA and became a film cutter... and took care of her until she died.. just about when my parents married. But he still liked science and I suppose I wanted to emulate him. He told me I could be anything I wanted to be, bravado, but also sort of bolstering for a girl of thirteen in 1955. I wasn't bad at science, it turned out, but was no whiz bang at it. (I have friends who were, so I recognize the difference.)
I started out liking school for science, i.e., career, life calling. Not too long after that, I switched majors to english, which we all know is near useless for jobs except for the lucky, but Wordsworth bored me to tears, so I switched to Psych, since I liked Psych 1A. But, alas, my science background made me growl at psych experiments of the time, as in psych 1b, pah, so I switched back to microbiology. And worked my way through that.
After twenty plus years, starting in high school and until I was 40, I worked in and around medicine, but I got more and more interested in art generally. What fool would do that as a way to get ahead? I had taken art classes after work for eight years when I chucked medicine and signed up for landscape architecture classes, not by any means cheap. That because I thought I would like it, sounded like fun, and also, maybe later I could get a job. I did like it, learned what the word design meant, no clue before that, and romped through the classes. When I started those classes, I quit my last lab and looked for a beginning job in the new field.
Nabbed one, another whole story, but interesting experience. You can say you know me as a designer of a major museum exhibit on land use. You can say I'm a fool underling who tried to have an exhibit not go to hell and pretty much failed. It was a new world. Things got better, but not really remunerative. But, I liked what I was doing the next 25 years.
In retrospect, I should have noticed myself drawing house plans at 11.
But if I had, and aimed then to be an architect, would I have experiences as much as I did?
So, on education, I'm a fan of a book Boomer sent to me, Shop Class as Soulcraft, by Matthew Crawford.
But I'm also a fan of keeping knowledge going in many fields, whether or not all that brings jobs.
