its the same amount, regardless of who you are, but its a higher percentage of income for the poor as opposed to the middle class or higher. i'm a typical Upper Middle Class Tech dude. when i want to buy a 60 inch LCD, i do it. do you think i even worry about tax? on the other hand, my father makes next to nothing so even if he could scrape together the money for a TV, the sales tax, of several hundred dollars, would be a pretty significant hurdle, and has to be taken into account when making the purchase. And, since its not reflected in the price it may come as a shock. when added to the bill.
I've always thought some of the taxes we pay are silly. trying traveling, and renting a car.... in Dallas. you will pay 40-50/day for the car, and 40-50/day in taxes. its insane.
