I'm sorry but that is simply NOT the case at least in the state I reside in which, BTW, has NEVER had a state income tax, relies on a sales taxes for it's funding, and is currently running the largest budget surplus in it's history! The state is Texas and you can check me out if you want.
It will be more of the same.
Yep! Hallelujah!
Its nice you feel that way. The reality is, even with the lower sales tax rates there is massive avoidance and quite a bit of business making tax-free business purchases that are really for personal use. It is a very difficult thing to police. Once a business buys something, it is difficult to tract how it was used.
