When was the last time you've seen any tax go away altogether (and not replaced with another one)?
And if it goes away, the retailer will just raise the prices. That's what happened when some government fee on airline tickets got eliminated south of the border. Ticket prices never changed. -- If you have an apple and I have an apple and we exchange these apples then you and I will still each have one apple. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas. George Bernard Shaw
