In some countries they do. Sweden requires all such state-sponsored educations to give students enough knowledge to make them eligible for admittence to university, should they want to. (It's "free", kind of. And if you pay for it yourself and get it from a private school you learn what you like/need.)newfangle said:Why don't trade schools do it with plumbers?
The assumption is that such education might be useful later on, as things are shifting fast enough to possibly require people to switch careers several times. Having learned how to learn at least, on several levels and different subjects, gives you an advantage then. (Btw, do you really expect mathematics to be a useful meal-ticket on its own?)
So if you were living in a society where the state guarantees free education, and is a democracy, the answer would be that it's a political decision taken in democratic order, for collective long term competitiveness reasons. (If it pays off remains to be seen.)
But since you're paying for it yourself, and the impetus for making you take classes like that seems to be not to crank out technocratic egg-heads, but "well rounded" characters, I think we can assume that you're up against the inertia of Traditional Academia. (That's their assumption of what a few weeks of history etc. might do for you, I'd think.)
And they'll get away with it if the educational institution is good enough. You want the rest of their product, yes? Well, then these are their conditions, and presumably, even if you're paying, there are others who might like your spot, no?

What makes you think specialisation was the key to their success? The specialist might be completely barren when it comes to thinking up the new stuff. That's the thing about specialisation; it's tailor made for already known and specific tasks, not for coming up with something new.newfangle said:Oh, and would it make sense to tell Einstein there's more to life than physics? Or Gallileo astronomy? Or Michaelangelo art? Puhleeze. Humans specialize for a reason.
Gallileo did a bit of everything, like any Italian courtier; party entertainment, military engineering etc. He learned a lot just pottering about in the Arsenal in Venice.
So did Michelangelo. Heck, when he started on the Sistine Chapel he had to write home to Florence to ask his old masters about the basics of al fresco painting. He had taken the class once, just never actually used it.
And Einsten, well he was a second rate student, and getting a not to onerous job in the Patent Office, technically a career dead-end, was what allowed him the free time to develop his theories. Had he been a successful specialist there's no way he would have had the time to do that. He would have been to occupied solving already eisting problems.
