>Meanwhile I got a broader education, but the majority of it isn't very relevant on a day to day basis, if ever.
While I agree with your core sentiment, my opinion is that this is a symptom of a cultural/societal problem and not one of the schools. Modern Universities are certainly ripe with problems (largely driven by adopting business structures), including generally poor quality courses and curriculum within them, but I think you've identified a larger societal problem we have.
Why is it that broad education which is generally, at the very least in my opinion, clearly valuable yet so lowly valued in society? It's my opinion that we have institutional structures that, given a lack of opportunities, value specialized and specific knowledge over general knowledge.
Meanwhile, if you have the capability to escape these institutional shackles, general knowledge becomes far more valuable. On the labor side, labor markets are all about jobs and specialized roles with efficient production from that role. On the capital side, you need more general knowledge to see, connect, and sieze opportunities. It seems to me that most lack enough genuine realizable opportunity where general knowledge becomes valuable (say, seeking entrepreneurship) and in such a set of constraints, it makes complete sense why people specialize and chase demand of specialization because it's their most optimal strategy for financial success.
I work in R&D in startup-esk environments and my general knowledge is fairly well valued, however even here leadership sometimes fail to see how some book or article I read years ago, course I took, project I worked on years ago, etc. was critical to making the connection that made this research thing possible.
They value the general subset of knowledge I have that made their thing possible (oh boy you know A, B, and C and those saved us!!!), never mind the hydrology work I've done, it's irrelevant (D, or so they think, even though I may draw on concepts from such domains opaquely) or perhaps hours of video gaming (E, which lead to a game theoretic intuition about approaching an underlying problem). That knowledge was only appreciated after the fact because it made someone a pile of money or positioned a large contract.
I remember hating taking geology in college because "I'd never use it," then I did a lot of applied science and R&D in the fossil fuels industry and suddenly a lot of "silly" things I did in geology gave me a foundation to jump from and to build upon. That silly geology course made me boatloads of money in retrospect. Throughout my career I always like to look back when I have a problem and say "ah ha, I sure am glad I studied or read about X years ago, that's one less thing I need to internalize now to do this thing." I'm always surprised how much old general knowledge I draw upon for new problems and how valuable they truly are.
