Economist Russ Roberts and Hoover Institution research fellow has released two new videos where he addresses some important issues and questions including whether America’s middle class is either stagnating economically or disappearing, how the American economy has been treating the middle class over the last 40 years, how wages and income should best be adjusted over time for the effects of inflation, how the increase in the number of retired Americans and changes in family structure have affected middle-income earnings, and whether all of the gains from economic growth have gone to the rich.
