From Inside Higher Ed.
It is a familiar enough story, but useful to rehash. Graduate students and adjuncts are cheap labor. They fill untold numbers of sections and receive miniscule pay and laughable benefits, if any. But graduate students receive tuition remission, you say. True enough, yet this is an exchange administrations can live with. If universities couldn’t afford to forgo the tuition, they wouldn’t. In return, the university places 20, 25, 30 freshmen in a classroom with a part-time instructor where it otherwise would have to place a comparatively expensive professor who enjoys a modest salary and other benefits. From an administrative point of view it’s a system that works.
