 This is Fresh Air, and if you're just joining us, my guest is David Matland, a senior fellow and advisor to the American Worker Project at the Center for American Progress, which is an independent nonpartisan policy institute. We're talking about the resurgence of manufacturing jobs and the union movement in America. Matland is the author of two books, including Hollowed Out, Why the Economy Doesn't Work Without a Strong Middle Class, and he's written for several publications.
