The Rich Get Poorer
According to the most recent IRS data, between 2007 and 2009, the 99th percentile income (AGI, not inflation-adjusted) fell from $410,096 to $343,927. The 99.9th percentile income fell from $2,155,365 to $1,432,890. During the same period, median income fell from $32,879 to $32,396.
These recent numbers illustrate the broader phenomenon, discussed in this paper, that high-income households have riskier-than-average incomes.
