With U.S. inequality at its highest point since 1928 and Wall Street bonuses hitting pre-2008 levels, DN! looks at the 100-year history of secret collusion between Washington and the financial industry. In her new book, "All the Presidents' Bankers: The Hidden Alliances that Drive American Power," financial journalist Nomi Prins explores how a small number of bankers have played critical roles in shaping a century's worth of financial, foreign and domestic policy in the United States. Prins examines how these relationships have influenced events from the creation of the Federal Reserve, the response to the Great Depression, and the founding of the International Monetary Fund and the World Bank. Now a senior fellow at Demos, Prins is a former managing director at Bear Stearns and Goldman Sachs, and previously an analyst at Lehman Brothers and Chase Manhattan Bank.
