Feeling stuck in a low-paying job? Barbara Ehrenreich has been there. Best known for a foray into marginal employment for her bestselling book, Nickel and Dimed: On (Not) Getting By in America, the author will kick off Ohio Wesleyan's 2009-10 Sagan National Colloquium this Tuesday with the discussion "What Renewing America Means to You." A few of the guest lecturers coming this fall are Nathaniel Fick (One Bullet Away: The Making of a Marine Officer), New York Times environmental reporter Andrew Revkin and NPR correspondent and author Andrei Codrescu. -Nikki Davis
