Can you imagine the screaming when people realize that Local, State, and Federal taxes, all combined into a single sales tax, increase the price of a product by 50% - 60%?
I hate taxes as much as the next guy, and I know that we need them to pay for government services. However, I am 100% against property tax, because it has no bearing on your ability to pay. I am for some sort of flat tax, whether it is sales or income. If we could trust people to report their income, I would go for income tax with only one area of deduction: Business could deduct cost of doing business - Tax only the margin. However, since too many cheat the system by under reporting, sales tax is the only viable answer for personal taxes.
Do you want to hear the inevitable scream against this system? It will be deemed unfair, because the "rich" will pay less BASED ON THEIR INCOME then the poor.
