People arguing against taxing the rich love to use percentages, and statistics, and always point at the people who don't pay any income tax at all (ie desperately poor people). You never hear them talk about the dollar figures, because you get a lot more sympathy if you say "I have to pay 55% of my income in tax" rather than say "I made 100 million and only got to keep 45 million. Poor me! However will I be able to care for my family?" 

As Homer Simpson said, "Oh people can come up with statistics to prove anything Kent. Forfty percent of all people know that."
