There's a lot of options other than simply offshoring.
Consider externalizing costs, almost no one has a servant pump gasoline for them, I would imagine you have to be very old for "self service gas station" vs "full service gas station" to mean anything to most Americans.
Another option is political corruption, I'll donate $ to your re-election campaign if you create a property tax free zone for my business.
The point is still valid in the states that aren't New Jersey or Oregon. In Nebraska, Washington, California, Iowa, Ohio and Kansas, all the places I have lived in or worked in my memory I have seen no gas station attendants.
This is largely because the cost and labor of operating the pump has been externalized by pushing onto the car operator.
Retail business do this with cash registers. How many of these jobs will simply disappear? What else can be fully automated?
