Background: Buoyed by victories in World Wars I and II and the end of the Cold War in 1991, the US remains the world's most powerful nation-state. The economy is marked by steady growth, low unemployment, low inflation, and rapid advances in technology. The biggest cloud over this affluent society is the distribution of gains—since 1975 most of the increase in national income has gone to the 20% of people at the top of the income ladder.
