Janet Yellen's career has shattered several glass ceilings; she was the first female head of the Federal Reserve, and she's now the first woman serving as Secretary of Treasury. In this episode, author and journalist Jon Hilsenrath discusses his new biography of her, Yellen, and how her upbringing and marriage reveal a lot about her professional path. Hilsenrath explains to Here & Now's Scott Tong that the love story of Yellen and her husband actually offers insight into the delicate line between democracy and capitalism, and how in a time of economic upheaval, policymakers are bound to make mistakes.
