You never said what your answer was, you posted a graph and said it is hard to put a number on, or some such. It's a simple question, if the cry is the rich don't pay enough of their income, what percentage should they pay?
Flat tax, yeah that'll work. Those people whining because they rich are only in 40% tax brackets etc, would really be happy if a flat tax was passed and everyone only paid 12%. Or would it be a not so flat tax and the rich have to pay more?
