It is commencement season, and President Obama has two graduation speeches to deliver this week to students who take with them a diploma, and significant student debt. ABC News reports student loan debt in the US topped one trillion dollars last year. Economists worry that new graduates entering the work force will have so much debt, they will hold back on consumer spending and not get mortgages for first homes, and that will hold back economic growth. The Obama administration passed significant student loan reforms a couple of years ago but these tweaks, without action by Congress, would allow some graduates with older loans to cap monthly payments at 10% of their low, starter salaries. The President also wants graduates to be able to re-negotiate their interest rate, like a mortgage.
