although i envy your enthusiasm you really got Obama's entire policy completely backwards.
If you wanted to make this experiment truly realistic and practical you would've taken the portion of your bill that was going to go to the rich fucker sitting comfortably in his mansion collecting $$$ and given that to the waitress along with her usual tip. And the bum would still be sitting on the corner making more meaningless signs and trying to wash your windows with piss instead of trying to earn his/her income.
