While America certainly has its share of people in chronic poverty and those with vast wealth, we are an economically mobile society. IRS data tracking the same group of taxpayers between 1999 and 2007 showed that Americans can move from one economic group to another fairly quickly. For example, nearly 60 percent of taxpayers who began in the lowest income group in 1999 moved to a higher income group by 2007. Conversely, roughly 40 percent of taxpayers who started out in the highest income group moved to lower income groups within eight years.
