A flat tax is NOT in any way a sales tax any more than any other income tax is a sales tax. Sales taxes at a national level are every bit as bad as the progressive income tax.
I didn’t say a flat tax WAS a sales tax. I said a flat tax ENTAILS a sales tax. It’s the only to make ends meet. Even conservative think tanks were estimating a federal sales tax of 22 percent would be needed to make up for the reduced income tax revenue.
