Actually, I don't know if it does, nor do I care. I will certainly not be looking into tax laws to see how much more taxes I can pay.
"When the advantage is due to government laws that apply inconsistently,'
Not government laws, state laws. Each state has it's own right to apply sales taxes or not. And every American is free (for now) to travel to any state and purchase goods.
The government and it's excessive taxation can kiss my hiney.
That does appear to be a majority opinion here at FR. Just know that these are not voluntary laws, and if you are caught, since you aren't an Obama appointee, you will be punished.
But as many have noted before, there's no chance you could get caught. For myself, I feel character is what you do when nobody could know the difference. But it is taxes, so most people feel it's there job to violate as many tax laws as they can get away with.
