NEVER MIND that the higher education plans of tens of thousands of students will be disrupted. Or that 8,000 people will lose their jobs. Or that American taxpayers could be on the hook for hundreds of millions of dollars in forgiven student loans. What is apparently of most importance to the Obama administration is its ideological opposition to for-profit colleges and universities. That’s a harsh conclusion, but it is otherwise hard to explain why the Education Department has unabashedly used administrative muscle to destroy another company in the beleaguered industry.
