New York Attorney General Andrew Cuomo's quest for the Governor's seat is exposing a deep flaw in the relationship between student loan companies and universities.

According to the New York Times [registration required], Cuomo's investigations led to the dismissal of Columbia University's financial aid director yesterday after the release of documents showing he promoted a student loan company -- Student Loan Xpress -- in which he had a stake, sending letters to parents and alumni on three occasions praising the lender.

Columbia joins other schools including Johns Hopkins and the University of Texas, Austin that have been caught up so far in this scandal. The fundamental problem is that schools don't pay much money to their employees even as they keep raising tuition. As with the rest of the U.S. economy, the gap is covered by debt -- in this case student loans.
