I never said it would cost nothing to administer, only that it would be substantially less. 45 out of 50 states already collect state sales tax. This would be done the same way, and by the same mechanisms.
23% percent on our income, 23% or close to it on everything I buy could potentially dwarf what I pay on my income.
Please tell me how much of each paycheck you currently
don't recieve due to federal withholdings? I know for me it's greater than 23 percent. Plus, everyone gets a prebate to offset a part of that 23 percent (for a family of four that amounts to around $6700 per year). Finally, you'd only pay that 23% on what you spend, not on what you earn, and only on new goods and services.
And prices would go down; that is how the free market works. Not for every item, and not necessarily instantly, but in general. Of course, I buy Arizona brand jeans, and they are much cheaper than Levis already
.
The underground market thing is going on already, as well as rampant income tax evasion. The simpler the system, the easier it is to monitor and police. Will Fair Tax eliminate all underground dealings? Of course not. No system is perfect, but I believe the Fair Tax to be far superior to the economic health of our nation than either a flat tax or the current system.
