I don't disagree. But here's another point. In my view, the most fundamental things to teach would be the ability to keep an open mind, and intellectual honesty (being able to put aside your ego and admitting where your argument falls short). Also a respect for learning and education, even without the expectation of a concrete financial reward. Despite universal schooling, I would say these values are anything but universal, at least where I grew up.
