waitlisted to northwestern, what does this mean for other top-tier schools? I am really scared

I mean if you think about this logically, many seekers of prestigious universities are most likely high-achievers and dream big. This also perhaps means that many seek higher salaries and positions, which in a lot of cases requires procurement of a professional degree of some sorts. So many top-tier university applicants (myself included) intend to pursue professional degree. If it doesn’t matter what undergrad one goes to in order to get to the professional degree, why blow $60000 a year in the first place?
