What exactly do you want?
You dont want to pay anything at all?
Are you one of those crazies who believe that taxation is unconstitutional?
From the towelheads living in the Afghan caves to rich snobs on the French Riveira, nobody likes to pay taxes but we need SOME revenue man. Even if Cain cuts like crazy which no doubt he will, there has to be SOME revenue especially for a country as large as the USA.
No doubt some exemptions will be made, for example even in the communist UK, VAT of 20% is not applicable to books and food items if i am not wrong.
let's look at some other countries
I believe Singapore which has one of the most competitive and productive economies in the world has a 10% VAT, 18-20% max income tax rate. Hong Kong regularly cited as the freest economy in the world has no sales tax, 20% max income tax, but then its security needs are taken care of by the Chinese government. It does not need to maintain a sizeable armed forces like Singapore.
My point is all these things cost money, You have to pay at least something.
9-9-9 is the best option for the USA.
