Good point. As a former highschool teacher, I tend to think on this (K12 in US terms?) level, but of course universal higher education wouldn't work. Some comments though. In my experience this point in life when people will figure out their direction varies wildly. I had classmates who figured it out in their early teens and others who found their way in late twenties. And even more important point against specializing too early - some of them had already three careers (I'm in my sixties). Times change, jobs disappear and strong universal foundation helps enormously if you have to start a new career.
