Democratic Sens. Sherrod Brown of Ohio and Elizabeth Warren of Massachusetts said the U.S. government is making too much money from federal student loans and called for changes in the loan system. Their comments followed a report from the Congressional Budget Office forecasting a record $51 billion profit this year from student loans. The projection is based on lifetime earnings from loans. "It's wrong that our students are being saddled with high interest rates and a lifetime of debt, and it's time that we give our children and grandchildren a break," Brown said.
