Ronald Bailey on Your Surprisingly High Chances of Being Both Rich and Poor

Washington University sociologist Mark Rank slices and dices income mobility data from 1968 to 2009 to find that 85 percent of Americans will experience income insecurity before they reach age 60. On the other hand, nearly 77 percent of Americans will have lived in a household earning more than $100,000 for at least one year, and 21 percent will have enjoyed living in households earning $250,000 for at least one year. Reason Science Correspondent Ronald Bailey trawls the data for insights about your chances of economic success or failure or both.
