Wage vs housing cost
Can a prospective employee afford to live in the area where the job is offered at the sage offered? If not, then reasonable access could mitigate the situation. If one can't afford a car needed to get to work, then there might as well be no job to fill. Presumably, genuinely needed employees will be offered enough to live close to the area. Supply and demand still work. North Dakota is hiring if you have a place to live like an RV.
