Sen. Dick Durbin [D-Ill.] recently proposed a bill that would dramatically change the way federal money can be allocated to for-profit colleges. Currently, for-profits are bound by what’s known as the “90-10 rule,” which says that 10 percent of for-profit college and universities’ revenues must come from sources outside of federal student aid. But G.I. Bill benefits can be counted towards the 10 percent, making them a lucrative source of revenue for the for-profits.
