It's not necessarily about eating 5x as much...or buying 5x as much...it's about buying the one items that cost 2-3 and even 5 times more than the norm. Texas and Florida seem to be doing pretty well under their tax system/economic plans, and to simply think the vast burden is going to fall on the poor is as much as a myth as believing that voter id requirements will suppress minority voting.
Texas is the Saudi Arabia of the United States.
Florida is the most popular tourist destination in the U.S. They get more money from tourism than from any other industry.
NC has very little in the way of oil or gas like Texas and while we have a decent tourism industry, it is nothing like Florida.
All states are not equal so you cannot say "It works in state x so it will work in state y too."
I'm not saying it WON'T be a good thing, I just don't see how we make up for the lost revenue and don't think it will work in NC. We don't have the ability to rely on outsiders (whether visiting as tourists or buying natural resource exports) to take the burden off of residents like Florida, Texas, Alaska, and Nevada can.
You're also crazy if you think that wealthier people consistently purchase things that are costing several times the norm. It just doesn't work like that. Some things yes, but the majority of wealthy people are just normal people.
One last thing, it is not about the overall burden, it is the burden in proportion to income. Increasing the consumption tax on poor people and lower middle class people will simply push more people onto government support programs to make up the difference. They currently pay very little, and sometimes nothing, in state income tax, yet they still struggle to make ends meet. If their cost of goods goes up with increased consumption tax, they're losing ground and more will end up on welfare programs.
