Prior to that, Jason Furman, a senior fellow at the Peterson Institute, says economic problems have been increasing since the 1950s. Alice Rivlin, a former vice chair of the Fed, says the U.S. political system's so polarized that the country isn't getting anything done. Jacob Frenkel, chairman of JPMorgan Chase International, says geopolitics are the sources of economic uncertainty. Finally, Alan Blinder, a former vice chair of the Fed, says the U.S. isn't going back to the nominal interest rates to which investors had become accustomed.
