In the depths of the Great Depression, many Americans lost their faith in a democracy that allowed an enormous gap between the wealthy and the too-often desperate poor. In “Created Equal,” the latest episode of the “Democracy Test,” Presidential biographer Robert Dallek tells us how Franklin Delano Roosevelt restored faith in democratic institutions and built the modern welfare state. We also hear how inequality ballooned again over the past fifty years, how that corrodes democracy, and what we can learn from our history about finding new solutions.
