In the years before the mortgage crisis, financial regulators often looked the other way as banks and other lenders pursued reckless activities that cost investors, taxpayers and borrowers billions of dollars. When trouble hit, these regulators had to scramble to fix the mess that their inertia had helped create.

This same dismal pattern is now playing out in the for-profit education arena.

For years, federal and state regulators have done little as dubious operators of for-profit colleges and trade schools have pocketed tuitions funded by taxpayer-backed loans. Many students left these colleges with questionable educations and onerous debt loads that cannot be erased in bankruptcy.

Regulators have finally woken up to this ugly reality. And, once again, taxpayers and borrowers will pay the price of regulatory failures.

Last week, after years of being on the financial precipice and facing accusations of improper recruiting practices by authorities in several states, Corinthian Colleges, a for-profit education company with 74,000 students in more than 100 locations around the country, began to wind down its operations. In an agreement with the federal Department of Education, Corinthian said it would halt admissions and try to sell 85 of its campuses.
