Paulina Cossette spent six years getting a doctoral degree with the goal of becoming a university professor. But it wasn’t long before she gave up on that path. With higher education under political assault, and opportunities as well as job security diminished by enrollment declines, Cossette felt burnt out and disillusioned. So she quit her hard-won job as an assistant professor of American government at a small private college in Maryland and used the skills she’d learned to go into business for herself as a freelance copy editor. Now Cossette is hearing from other newly minted Ph.D.s and tenured faculty who want out — so many, she’s expanded her business to help them leave academia, as she did.
