There is possible legal problems if BK paid 50% more for tomato's if the tomato provider turned out to be my uncle. To pay more taxes voluntarily is not good business practice. I didn't hear a peep when GE paid NO taxes on billions in profits. Buffet works his taxes by making his living off of a top rate of 15% on dividends. When he was crying for more taxes on his money, all he had to do was write a check to the treasury for whatever guilt he felt. To insist everyone else pay more is just BS.
