Under current policies the federal debt will rise from 78% to almost 180% of U.S. GDP in three decades. In his new book, "Fiscal Therapy: Curing America's Debt Addiction and Investing in the Future," Brookings Senior Fellow William Gale explores policies to raise revenue, control spending, and increase public investments, and solve our debt problem. In this episode, Senior Fellow David Wessel interviews Gale about his new book and policy ideas. Also, Christen Linke Young, a fellow with the USC-Brookings Schaeffer Initiative for Health Policy, answers a listener's question about why health care costs so much in the United States.
