It's interesting that the labor cost doesn't seem to make _that_ big of a difference, compared to other variables like taxes. New Jersey has one of the cheapest gas prices in the nation but is one of the few states that forbids motorists to pump their own gas. I don't think it's due to logistics either, since neighboring PA and NY have much higher prices. I'm guessing it's just the taxes? What else could it be?
