As we have discussed, from 1979 to 2007, inflation-adjusted incomes of the top 1 percent of households increased significantly versus the rest of the wage earners (i.e., the remaining 99%). Those even better off, the top 0.1 percent (the top one one-thousandth of households), saw their incomes grow 390%.
In contrast, incomes for the bottom 90 percent grew just 5 percent between 1979 and 2007. All of that income growth, however, occurred in the unusually strong growth period from 1997 to 2000, which was followed by a fall in income from 2000 to 2007.
