Why is it "Class Warfare", when it is fair for working families?

President Barack Obama on Monday made an impassioned plea for what he described as his balanced plan to reduce the deficit, arguing that his proposal for a so-called "Buffett rule," which would prohibit millionaires from paying a lower tax rate than middle-class Americans, is not "class warfare" as Republicans have charged.

"All I'm saying is that those who have done well, including me, should pay their fair share in taxes," Obama said, adding that he would veto any legislation "that puts all the burden on closing the deficit on ordinary Americans."
