What is happening, or what should be happening, on college campuses has rarely, if ever, been a topic of the remarks of Donald J. Trump, the presumptive presidential nominee for the Republican Party.

The “Issues” section of his website has only this related to education: “I will end common core. It’s a disaster.” And this is accompanied by a 51-second video expanding on this theme.

However, recently, Trump’s campaign co-chair and policy director, Sam Clovis, gave an interview to an education website, Inside Higher Ed, that outlined what a Trump presidency could mean for the nation’s 6,000 colleges and universities, and its over 20 million post-secondary students. Clovis is a professor of economics at Morningside College, a small private institution in Iowa, who is currently on leave in order to work for the campaign.

The major theme that emerged from the information he provided was that as president, Trump would improve student success by reforming the federal student loan program in two ways: 1) change the student loan program so as to provide more incentives for colleges and universities to enroll students who will be successful and earn enough money upon graduation to pay back their loans; and 2) to return the federal loan program to its pre-Obama status by having the loans come from private lenders, rather than the federal government.

I am a provost and a researcher of education economics. And here’s what some unintended consequences of these proposals would look like.
