It's difficult to get a job and people stay in school longer because they're employed as teaching assistants or instructors by their schools, by their schools where they're graduate students, and that does become exploitative eventually because they're very cheap labor and there's a way in which in it's not in the institution's interest to give them a degree if they can continue to employ them, I don't think anybody thinks that way, but effectively that's the way the system is starting to work.
