If you’re an adjunct at CUNY, you make about $3,000 per course.
With an army of teaching assistants and graders.
With travel and research funds.
While you’re getting boatloads of money for teaching at USC (“You won’t believe what USC will pay per week,” Petraeus kvells in an email to Ann Kirschner, the dean of the CUNY honors college where Petreaus will be teaching).
Gawker has the whole email thread, plus some other documents they got through a Freedom of Information Law request.
