lol. I like how you assume that what Obama is doing is not based on research.
I promise he doesn't like taxes any more than you do. He's just looked at history and seen that during our best periods of of economic prosperity have involved some higher taxes (see the 50's and 60's) and some of our worst times have involved lower taxes (see Calvin Coolidge and GWB). I'm sure it's much more complicated than that.. and much more research has gone into it than I have put in.
Obama does not go off of principal or personal philosophy, he goes off of historical event, facts, figures, numbers, research, etc. He consults people who are experts in their field.
