NYU

New York University offers one of this country's most expensive four-year degrees, and it's only getting more expensive.

John Sexton has been president of NYU for over a decade. During that time, the university's real-estate footprint has grown by two million square feet and it's launched 11 international academic centers. Sexton has faced significant criticism for the direction he's taken the school, and for rising costs. Earlier this year he announced he'll step down in 2016.
