The White House has come up with a fun widget that will be sure to infuriate you this tax weekend.
They note on the site that "about 55,000 millionaires pay a lower effective tax rate than millions of middle-income Americans. I used the calculator to find out that at least 48,700 millionaires paid a lower effective tax rate than me in 2009.
Fun with income inequality! Tell your senators to start fixing that, and pass the Buffett Rule.
