There are now nearly 40 colleges in the US where a 4-year degree costs more than $250,000

As shocking as that number is, it's not hard to believe given the cost of college today - though it calls into question whether the current model of higher education is sustainable.

There are currently 38 US colleges that cost more than a quarter of a million dollars to attend for four years.
