55% of students receive aid, and of those that receive aid the average expected contribution is ~15K. So technically most students do not pay that amount, although 45% is higher than I was expecting to be honest.
Also per that NYT article on wealth at colleges ~15% of Harvard frosh come from the top 1%, so that's a decent chunk of the remaining 45% that clearly don't need aid and likely did not even apply for any.
I doubt you will find many people out there that feel they paid too much for Harvard. Certainly there are bigger fish to fry as far as college tuition rip offs.
