To Joseph Stiglitz, the Nobel Prize-winning economist, the strange behavior of the economy can be traced to the growing gap between wealthy Americans and everyone else. In his new book, "The Price of Inequality," he connects surging student loan debt, the real-estate bubble and many of the country’s other problems to greater inequality.
Stiglitz has taught at Yale, Oxford and MIT. He served on President Bill Clinton’s council of economic advisers, then left the White House for the World Bank, where he was the chief economist. He’s now a professor at Columbia University.
