HIGHER EDUCATION BUBBLE UPDATE: High Debt and Falling Demand Trap New Vets.

At the age of 30, she still has the sign, which is framed on her desk at the Caring Hearts Animal Clinic in Gilbert, Ariz., where she works as a vet. She also has $312,000 in student loans, courtesy of Ross University School of Veterinary Medicine, on the Caribbean island of St. Kitts. Or rather, $312,000 was what she owed the last time she could bring herself to log into the Sallie Mae account that tracks the ever-growing balance.

“It makes me sick, watching it increase,” she says. “There’s also the stress of how am I going to save for retirement when I have this bear to pay off.”

They don’t teach much at veterinary school about bears, particularly the figurative kind, although debt as large and scary as any grizzly shadows most vet school grads, usually for decades. Nor is there much in the curriculum about the prospects for graduates or the current state of the profession. Neither, say many professors and doctors, looks very promising. The problem is a boom in supply (that is, vets) and a decline in demand (namely, veterinary services). Class sizes have been rising at nearly every school, in some cases by as much as 20 percent in recent years. And the cost of vet school has far outpaced the rate of inflation. It has risen to a median of $63,000 a year for out-of-state tuition, fees and living expenses, according to the Association of American Veterinary Medical Colleges, up 35 percent in the last decade.

This would seem less alarming if vets made more money. But starting salaries have sunk by about 13 percent during the same 10-year period, in inflation-adjusted terms, to $45,575 a year, according to the American Veterinary Medical Association.
