Why College Costs Are High?

From a Conor Friedersdorf piece on Yale:

These are young people who live in safe, heated buildings with two Steinway grand pianos, an indoor basketball court, a courtyard with hammocks and picnic tables, a computer lab, a dance studio, a gym, a movie theater, a film editing lab, billiard tables, an art gallery, and four music practice rooms.

When I went to college, while freshman dorm was heated and safe, its only frill was a lounge room with a TV.  And we had to walk uphill to reach classes, and uphill to reach the dorm.
