Nobel prize-winning economist Joseph Stiglitz, author of “The Price of Inequality: How Today’s Divided Society Endangers Our Future,” elaborates on the origin of U.S. income inequality, why it’s so slow to recover, and why it contradicts basic American values. “American inequality is not only inequality of outcome but inequality of opportunity. A sense of fair play, a sense [that] everybody has a chance to make it from the bottom to the middle, middle to the top — these are basic American values,” Stiglitz says, “and our inequality has undermined that.”
