For a long time now I’ve been writing about how student aid fuels explosive college costs, while Chris Edwards and Tad DeHaven have been highlighting the ever-cushier compensation of federal workers. Well, I’m pleased to have finally discovered a direct linkage between these topics: A new U.S. Office of Personnel  Management report on student loan repayment programs for federal workers.

According to the report, in calendar year 2009 “36 Federal agencies provided 8,454 employees with a total of more than $61.8 million in student loan repayment benefits.”

Now, 8,454 employees is a small chunk of the entire, roughly 2-million-person federal workforce. Still, $61.8 million isn’t anything to sniff at, and loan forgiveness is one more perk that needs to be considered when thinking of federal worker compensation. And then there’s the trajectory of forgiveness: According to the report, spending on student-loan forgiveness by federal agencies in 2009 was “more than 19 times” bigger than it was in 2002. Were things to continue at that rate, in 2017 the cost would be almost $1.2 billion, and then you’d almost be talking real money!

The important point from a student-aid perspective is to emphasize something that must never be forgotten: While many analyses of student aid will only count grants – because they don’t ever have to be paid back – as “aid,” the reality is that that hugely under counts the true cost of federal aid to taxpayers. In addition to grants, taxpayers fund all federal student loans (and eat them when they aren’t repaid), help finance work-study, and pay for federal expenses that people taking federal education tax credits don’t pay for. So when you look just at federal grants, the bill for taxpayers in the 2008-09 school year was about $24.8 billion (see table 1). Add in loans, credits, and work-study, however, and the bill suddenly balloons to nearly $116.8 billion.

“But wait,” will say the only-grants-are-aid crowd, “isn’t a lot of that $116.8 billion loan money that will be paid back?” Yup – it’s just that at least $61.8 million of that repayment is coming, once again, from beleaguered federal taxpayers. And that, to be sure, is just the tip of the federal loan-forgiveness iceberg.
