The growing $1.1 trillion student debt burden in the US has been well documented, yet concerns are subdued. That’s because the burden, unlike the housing crisis, won’t cause a sudden economic crash. Instead, it will prompt a slow strangulation of spending spread over many years. Congress has made some minor efforts to reduce interest rates on debt, but the necessity for such large loans must be scrutinized. And that means confronting the indulgences of colleges.
 
 Tuition costs have soared in recent decades. In 1973, the average cost for tuition and fees at a private nonprofit college was $10,783, adjusted for 2013 dollars. Costs tripled over the ensuing 40 years, with the average jumping to $30,094 last year. Even in the last decade the increase was a staggering 25%.
 
 The ability of colleges to raise costs has been facilitated by a sharp increase in federal student aid. Lenders freely dispense credit to students, safe in the knowledge that all loans are guaranteed by the government. Between 1973 and 2012, federal aid (inflation-adjusted) increased more than 500%. Looking at a shorter period, between 2002 and 2012, total federal aid to students ballooned an inflation-adjusted 106% to $170 billion.
