Last year, the United States reached a troubling new milestone in higher education: for the first time, total student loan debt in the United States exceeded total credit card debt. It’s a development that should have come as no surprise. Over the past 15 years, the amount that students borrow to finance their postsecondary education has grown by every available measure: between 1993 and 2008, the percentage of bachelor’s degree recipients who borrowed for their educations jumped from 49 percent to 66 percent, with average total debt at graduation increasing over 50 percent, from $15,149 to $24,700. Borrowing money to go to college, like borrowing money to buy houses and cars, is fast becoming a fact of American life–and so, it is turning out, is the struggle to pay it back.
