Surprise! Who's not paying federal income tax?

USA Today reports:

Amid complaints that nearly half of tax filers in the U.S. won't pay federal income taxes this year, this has been lost: Those making $75,000-$100,000 a year are the fastest-growing share of people who don't pay federal income taxes.

Not working poor people — but those who are firmly middle class.

They still make up less than 1% of the total number of income tax filers who pay no tax at all, but their overall number has exploded, from fewer than 5,000 not paying taxes in 1996 to nearly 500,000 in 2009, the most recent year of available data.

No word yet on whether George Soros will write a check so Van Jones can organize demonstrations against these people.
