Perhaps Princeton should stop requiring applications and just accept students chosen at random from 12th graders across the country. Then we shall see how the education at Princeton, supposedly superior, will work out.
Parents want to send their kids to "elite" universities, because of the perception that graduates of these places do very well.
The reality is that they do very well because the elite colleges are (or were) very selective, only admitting the smartest and hardest-working.
An elite university that stops admitting the smartest, most driven applicant, will descend into mediocrity.
It is easy for them. Liberal = good. Everything else bad. Nothing else need be considered.
