The distance in America between the “haves” and the “have-nots” is growing. Increasing returns to education have created a bifurcation in income distribution. The bottom quintile had seen its mean income increase 34.5 percent in real terms from 1967 to 2005, whereas the top income quintile had an increase in mean income of 80.8 percent over the same time period. Average income growth for the bottom three quintiles was only 30.4 percent. The typical Wal-Mart customer is in the middle-income quintiles.
