Zampa - I agree there are a lot of very, very bright students today. It's just this aspiration thing.
We spend so much effort boosting their egos without emphasizing that there's a price to pay. Well motivated students have always, and will always be fine.
The middle and less academically able either seem to have too much given to them on a plate and given higher qualifications than they actually warrant, which leads them into a false sense of security; or alternatively overlooked in schools (who only really care about league tables since that's what they get judged by), and are provided with an inflexible curriculum which is ill-designed or their needs and disaffects them completely. In these cases they get in the very dangerous habit of giving up, arguing the toss about even the most basic of common courtesies and blaming everyone else. This habit sticks with them for years.
