Cain is talking about 9% FEDERAL sales tax. After your state+local sales tax is added (mine is 8.25) you're at 17.25 percent sales tax. Cain ain't gonna make local and state sales tax go away.......
I understand that. But, reducing my federal tax down to 9% gives me a whole bunch of extra cash. Then add the elimination of capital gains and dividends, and I will be way ahead of the 9% sales tax. However I should note I am retired and do not buy a lot of stuff. So my sales tax is not huge.
You are right about local taxes....they will be here regardless and basically have a neutral effect.
