The basic rules of a market economy — even golden oldies, like a link between supply and demand — just don’t apply.

Legal diplomas have such allure that law schools have been able to jack up tuition four times faster than the soaring cost of college.

He ended with a challenge: If a law school can’t help its students achieve their goals, “we should shut the damn place down.”

Given his scathing critiques, you might expect that during Mr. Matasar’s 11 years as dean, he has reshaped New York...
