Elizabeth Warren has filed her first piece of legislation in the Senate, and its subject is no surprise. Warren, who campaigned on a platform that called for relieving the many unfair burdens she says are sinking middle-class Americans, is sponsoring a bill to dramatically lower the interest rate on student loans for one year while the government figures out a long-term reform to the student loan system.

The rate on federally-subsidized Stafford loans is set to double on July 1, from 3.4 percent to 6.8 percent, if Congress takes no action. Warren’s bill would go much further than simply freezing the rate; she would lower it to 0.75 percent, the same rate — not coincidentally — that the Federal Reserve currently charges banks for short-term loans. “If the Federal Reserve can float trillions of dollars to large financial institutions at low interest rates to grow the economy, surely they can float the Department of Education the money to fund our students, keep us competitive, and help grow our middle class,” Warren said in a May 8 floor speech introducing the bill, a populist pitch that has racked up more than 160,000 views on YouTube.

One problem with tackling the cost of higher ed at the loan-and-financing end of the equation is that it does nothing to put the brakes on inflation in higher ed. Indeed, many think the easy availability of student loan money only fuels further run-up in the sticker price colleges and universities charge. A new report from the New England Center for Investigative Reporting says Massachusetts higher ed institutions have been bulking up with new administrative positions at a rate twice as fast as they’ve added research or teaching faculty.

A Globe editorial on Saturday picks up on the concern that “rock-bottom” interest rates might only “exacerbate the bubble in higher-education pricing.” But the paper says Warren’s bill isn’t likely to contribute much to such a problem, as it applies only to Stafford loans, which are capped at $8,500 a year, it would only cover new loans, and the near-zero interest rate would only apply for a one-year period while Congress works out a long-term fix.

As such, says the Globe editorial, the bill is more symbolic than substantive, “designed to address a short-term problem while drawing greater attention to the broader and troubling crisis of student debt.” Grandstanding with a “mix of populist rhetoric and subterfuge” is how Jason Delisle of the New America Foundation put it.  

Everything from figuring out incentives that will push colleges to slow tuition inflation to the role of massive open online courses may figure in the effort to address trends in the cost of higher ed that many say are not sustainable.

However you characterize Warren’s bill, what’s clear is that she has only laid down a marker on, not offered a solution to, one the signature issues on which she says the middle-class is “getting hammered.” Whether we look back at it as so much grandstanding or the beginning of a long, Ted Kennedyesque march to grind away relentlessly at an important, but vexing issue, is the challenge facing the state’s new senior senator.
