Income inequality worst since 1920s, according to IRS data

The superrich are gobbling up an ever larger piece of the economic pie, and the poor are seeing their share of earnings shrink: new IRS data shows the top 1 percent of Americans are claiming a larger share of national income than at any time since before the Great Depression.

The top percentile of wealthy Americans earned 21.2 percent of all income in 2005, up from 19 percent in 2004, according to new Internal Revenue Service data published in the Wall Street Journal Friday.
