Earlier quoted context omitted.
That 57k is the lifetime amount for undergrad, not the per semester amount.
CMU is, I believe, the most extreme example at $65K per year: http://www.cmu.edu/hub/tuition/1516-undergraduate.html
CMU's tuition is indeed quite high, but it's actually 50k$ per year for undergraduates. The 65k$ you quote includes campus housing and dining services, so it's not really fair to compare that figure to tuition costs elsewhere.
