The Clinton's open their books, and they open with this line:
According to the most recent data available from the IRS, in 2005 taxpayers earning $10,000,000 or more paid on average 20.8% of their adjusted gross income in taxes.
While the low figure is likely a result of the low tax rate on long term capital gains, and rich folk gots them some monies on which to earn long term capital gains, that doesn't necessarily make me feel any better about it.
At least the Clinton's paid 33%... on their ~$13 million a year since 2000.
