whenever you purchase something, odds are, you will be paying taxes. Ok, its really a double taxation...the wages you received having already been taxed yet for some reason you must pay more tax when you use the money.

Yes, the founders went to war because taxes were just to absurdly high... at 4%. Wonder what they would think of our current system (which would make King George proud)
