Yeah, you have a legit point. But think about how much money that is for a second; the highest earning one percent of the country could sustain us for 4 months. Thats crazy. Anyway you do have a very good point. At the same time however, remember, they are being taxed per dollar exceeding a certain amount, so the idea that rich people will for some reason be non-existant is complete bs.
Also, Obama's tax plan is far less liberal than he claims. The reason I support Obama is because when he debates, he uses more facts than Romney. Also in the last debate, when Romney was asked if the math added up, instead of explaining how it added up, he explained that he was a business man, and as a business man he was able to do the math. Instead of explaining what exactly he would cut (PBS and C-Span take up %.014 of the budget by the way), he basically said trust me.
