In all seriousness, charging a car is far safer than filling it with gas; no attendants needed!
* so long as you believe the premise of the law
No one could reasonably look at the other 48.5 states and conclude that self-service fueling is dangerous. They could reasonably say “we want to structure fueling to protect bullshit jobs.”
And there I was sitting in my truck realizing I had about over 25 years "job" experience for what this kid was doing, and I had never done that.
Edit: I looked it up, the toast story is Erdős
Or does the cost just get absorbed into the supplier chain and cost consumers nothing while creating a few jobs in the process?
Nope. From what I hear, the increased cost of insurance for self-service is in the same ballpark as hiring a few attendants. So it's a wash.
If it were true, then there would be a business opportunity in the other 48 states for a gas station to sell full service gas at the same price as others are selling self service at. But it never, ever occurs, so it is trivial to prove the labor costs are material and would result in higher gas prices that people are not willing to pay for.
Unfortunately there's no easy way to tell, because in the other 48 states, full service is considered a premium service and they charge extra for it because a certain segment of consumers will pay for it. That doesn't mean it's actually more expensive.
This is disproven by the fact that in my 3+ decades of travel around many US states, I have never seen a gas station attendant outside of NJ and OR. No one is willing to pay the premium necessary to employ attendants, and so they will reward the gas station owner selling self serve for cheaper.
There certainly exists a population of people who would like to have others pump their gas for them. If gas station attendant labor costs made no effect on bottom line gas prices, then gas station owners would try to court these people by selling full service gas at the same price as self service.
Since it does not happen, the premise of negligible labor costs must be false.
Possible hypotheses:
1) Every single gas station in the US not in Oregon or New Jersey is run by complete idiots who can't figure out a way to make full service gas profitable despite the fact that "it's a wash."
2) What you heard is not correct.
What I'm pointing out is that the issue is not that insurance and labor costs wash each other out, or the rest of the country would have more than zero full-service stations.
Here is a recent academic paper that models the cost of labor: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4064061
Oregon gas tax is ~$0.38 per gallon ($0.10 extra in Portland). Washington is $0.494 per gallon.
The claim that labor costs for full service gas are not reflected in prices at the pump that customers pay for a low margin fungible good like gas is ridiculous to me. Even more trivial is the proof by way of 48 other states having no full service gas stations, with the only possible reason being that people do not want to pay the extra cost for someone else to fill their gas.
I live in Oregon, and usually I'd rather pump my own than wait for the attendant to start pumping, then wait again for them when pumping is done. I appreciate being able to do it myself on trips out of state (or in rural Oregon, where in some places self-service is now legal).
