Our guest this week is Matthew Hennessey. He’s an editor at the Wall Street Journal, and also the author of Zero Hour for Gen X: How the Last Adult Generation Can Save America from the Millennials (Encounter Books). It’s a fascinating read: part-political obituary of a generation that, squeezed between two larger cohorts, the Boomers and the Millennials, may have missed its historical cue; part-rallying cry because, as Matthew explains in our midlife crisis of a conversation, it’s not over yet. ‘It’s zero hour. Don’t just stand there. Bust a move.’ Presented by Dominic Green.
