Detroit (and the midwest auto industry) used to be like this - where whatever you needed was fairly close already. Not so much anymore. I'd have to dig up the cost difference in a slack (I asked about it), but IIRC, the majority of the price difference was not the difference in the cost of labor on a $30 item, but that at the scale things are being made the logistics isn't as expensive (you can buy 1000 chips and get them in a day or so rather than needing to buy 10,000 chips and needing for them to be shipped from 1000 miles away that will get here next week).
