So, yes, this is a strawman argument.
No, it isn't. I'm saying because all taxes have a tendency to go up, let's not give the Federals any new forms to add to their list.
Cain wants to add a Federal sales tax. He wants to make a bad situation worse. That's no strawman. It's 9-9-9.
But it's not accurate that "Cain wants to add a new tax."
Cain is proposing completely restructing the present tax code. If you replace one thing that has a total tax burden of (I'm just going to pick numbers here) 40% on the real economy as a whole and replace it with another thing that a total tax burden on the economy of 9%, isn't that a good thing?
Not to mention that it helps us very much along the road to more Constitutionally limited government.
