You can do this with State taxes too, but I think your impression that people just ignore it is correct. A good example of this is gas prices. Gas in CA is 70c per gallon, vs about 25c per gallon in the Northeast. This gets baked into the price, and is way more expensive in CA, but people need to buy gas. So you just have to pay. And since it is everywhere in the state, most people don't notice the difference.
