In the Boston Globe, Linda Wertheimer follows up on Jonathan Glater’s Times piece of a couple days ago, looking at the consequences of Harvard’s recent decision to enlarge its financial aid policies for families making up to $180,000 a year.

Most of the colleges doing away with loans belong to an exclusive group of roughly three dozen schools with sizable endowments - $35 billion, in Harvard’s case. Their shift is increasing pressure on less-affluent colleges to come up with new strategies to sweeten financial aid for a wider group of students, some of whose families have been calling admissions officers asking whether they would be offering no-loan aid deals, too.

Yet, even if all colleges could afford to eliminate loans, several admissions and financial aid directors say they would be reluctant to change a long-held tradition of holding students and their families responsible for part of college costs if they can afford to contribute.

Is it possible that students who don’t have to pay for college would feel less invested in the experience and value it less? Sure it is.

Philosophically, one of the dangers is we’ve made debt a four-letter word,” said Lee Coffin, the dean of admissions at Tufts, which this fall eliminated loans for students from families making less than $40,000 a year and will not extend the offer to higher-income families. “I wonder what it will do to a generation that will go to college without any personal sacrifice. You start taking loans away, and you start saying, ‘Here’s a free ride.’ “

But it also seems possible that many students who got a free ride to Harvard would come out of those four years with a deep sense of gratitude to the institution, perhaps one that would result in financial contributions down the road—especially without those pesky loans to pay off.

It’s fascinating to watch this debate that Harvard has sparked. This is a good conversation to be having, especially because we don’t talk enough about higher education (and education generally) in this country. Drew Faust deserves some credit for helping to spark this debate—and not feeling that she has to dominate it.
