If you paid for an undergrad degree at a research institution, and didn't understand that you should have been working in some famous professor's lab to actually get your education, you're going to be pretty upset when you get out.
And didn't understand... because someone should have taught you that when you were 14, so this basically blames the schools for not properly educating kids about the ways of the world. Fair enough.
I'd suggest it goes a little further though. The left has a bias or belief that problems are the fault of society, whereas the right tends to bias to the belief that problems are the fault of the individual. Now, the problem is that, the left tends to be more associated with education (because if society and its institutions are the problem, then those are the institutions which need to be improved, and education needs to be improved). So the left is more idealistic about the role of education. See it is implicit. But what you're saying is, from more of a right wing point of view, hey nobody should be an idiot, or ignorant, to the fact that the world is competitive and selfish place, and that individuals have to learn to handle this, mostly via self control and character building and smarts (so don't come crying when you become a victim).
And that, I think, is fair enough, as there is no real difference between the "individual" and "society", as ideological categories, because we are always both, we are all individuals and we all live in society and are part of social institutions. Individuals have agency. Groups have communion. And we always act and function in both. So the problems are often found in both places. (A way forward for politics is to become both left and right wing).
So I would just add that, I agree in the sense that, our society needs to spend more time acclimatising kids to "how the world works", as by nature, humans are both competitive and cooperative. And we need to be educated to understand when and where each one is the dominant driver. So I do agree, it is right to tell people that they need to wise up about American universities. But I wouldn't blame kids for not knowing that already, if they haven't been taught.
Sure sounds like someone advocating the smart middle instead of ideological lefts and rights. Yay!
