According to Politico:
In obscure data tables buried deep in its 2016 budget proposal, the Obama administration revealed this week that its student loan program had a $21.8 billion shortfall last year, apparently the largest ever recorded for any government credit program.
The main cause of the shortfall was President Barack Obama’s recent efforts to provide relief for borrowers drowning in student debt, reforms that have already begun to reduce loan payments to the government. For more than two decades, budget analysts have recalculated the projected costs of about 120 credit programs every year, but they have never lowered their expectations of repayments this dramatically. The $21.8 billion revision—larger than the annual budget for NASA, or the Interior Department and EPA combined—will be tacked onto the federal deficit.
“Wow,” marveled Steve Ellis, vice president of Taxpayers for Common Sense. “Whether or not it’s good policy to help borrowers with their payments, it’s obviously costly for taxpayers.”
