I can't speak for teaching at the University level, other than my time there, which wasn't that long ago (relatively). But, as I do see the students, right before they start, I have noticed a change in the mentality, over the past several years.
They are more self-centered, which says a lot, when talking about teenager. As I said already, they already have a sense of entitlement, which goes a long with that. To complicate matters, there seems to be more of the "Helicopter Parents" that you hear about. The parents do so much of the work, in regards to signing the student up for classes, checking the student's grades, and worst of all, doing the work for the student, that when the student goes on to college, they are incapable of adapting to the college format. So the student struggles, and has to play catchu p, since their parent(s) didn't let them learn how to be a student themselves. Or, there are the cases, where the parent continues "Hovering" throughout college. I've even seen stories of such parents getting involved in the job interview process. Guess what happens to those applications/ applicants?
There's nothing wrong, with want your child to succeed, but it needs to be on their own merits.
It's yet another way, how kids/ students are missing out on the opportunity to learn problem solving skills. "It's easier to just give my child the answer".
