As for 2, I think that's where the life experience of the parents weighs heavily.
For example, I'm deeply saddened when reading about scam private universities, because they prey upon people who value the ideal of "education" and really want to succeed, but don't have the people around them with enough experience of higher education to distinguish the good schools from the scams.
Couldn't agree more. Also, again from "Hoop Dreams", it was as though the basketball players believed that having entered college was going to transform their career prospects in itself, regardless of what they learned. If you see college as some sort of mysterious potion, then you might think any college will transform you. You don't see that college is at best a tool for developing skills that are relevant to building a career.
