Only on the "CBS This Morning" podcast, Pulitzer Prize-winning authors Nicholas Kristof and Sheryl WuDunn join co-host Tony Dokoupil to discuss their new book, "Tightrope: Americans Reaching For Hope." Kristof and WuDunn, the first married couple to win a Pulitzer for journalism, traveled from Kristof's hometown in rural Oregon to urban Baltimore to show how decades of government policies have failed working class Americans. They explain how the disappearance of blue collar jobs, along with stagnant wages, weak education and a lack of healthcare, have led to intergenerational struggles. Plus, they share the solutions other industrialized nations have adopted that helped them avoid the same sweeping drug problems, mass incarceration and declining life expectancy rate as the United States.
