The number of student loan borrowers in the U.S with loans over $100,000 has surged from about 1 million in 2010 to 1.82 million in 2014, according to the Federal Reserve Bank of New York. Th borrowers are graduate students who have piled up so much debt in the last decade that 40% of student debt of $1.19 trillion in 2015 is from graduate student debt. A major problem is that there are no limits to graduate student borrowing and the rates are higher because of bad loans in the system, increasing the size of the burden of student debt on individual borrowers rapidly, ironically at a time of low interest rates. This leaves borrowers worse off with unpayable student debt affecting them all their lives, taxpayers paying more, prudent student loan borrowers paying higher rates, and all the time reducing the pressure on universities and colleges to reduce costs for affordable graduate education. This is now a major problem in the U.S. and a major issue in the 2016 presidential election.
