I go to a top 20 university. We have a smattering of smart kids but a lot of unmotivated kids that only want to party and no intellectual pursuit whatsover. I've also been to a lot of the ivy league schools and observed a lot of the same things that I witnessed at my school.
Most surprising is the number of people I know who have never finished reading a book from cover to cover and cannot write anything for their life. Also a bunch of people I meet at my school and also the kids from my HS who went off to ivy league schools have major ADD and can't sit still to work or read anything remotely long without being distracted by social media or something. The kids from my floor last year spent the majority of their time playing xbox and getting high than do anything productive. I feel like a lot of my state school friends were better than this. Did these kids just get lucky with rich parents and figured out how to game the system? Can't be the whole school though.
