We have a series around here called “How to Be a …” where notable people tell us how they got their interesting jobs. Today, just in time for the holiday, we have Dominique Crenn. “Not everybody understands how to cook … they don’t have to know how to cook,” she says about people who work in her restaurants. “But I hope they can know how to eat.” But first: American household debt has reached a record high, topping its previous peak in 2008. We’ll look at what that means for the holiday season. Also at a record high: homelessness among students at the largest school district in the nation. We’ll look at why. Plus, a conversation with actor Frank Grillo about his new Netflix show.
