Getting back on target for a second, as a resident of Salem, Oregon, loki8481 is right in pointing out that line. To as far as I have seen, there is not a large number of people within the state who would traditionally work minimum wage jobs and now can't find them, the problem is continuing repercussions of tech fallout. Salem for example is losing its biggest private employer, Sumco USA, a silicon wafer manufacturer, as the head offices are consolidating the company towards the Cincinnati and Phoenix offices, and even that is just buying time and reducing the company to a point where it becomes a specialty manufacturer. Still, the company employed nearly 2000 people right before the start of the fallout, and they had a lot of contractors(electrical, etc) whose majority of business was with the company, not to mention they are the biggest user of resources in the city(better than half a mil a month of power and water each).
Their leaving in turn is undermining a whole lot of jobs, but as a technical facility, it was almost entirely staffed by skilled workers who had either BS/BA+ degrees, or over a decade and a half with the company. These people in turn often don't have another job lined up, since there simply aren't that many jobs of this type in the area. The fact of the matter is that the era of USA produced silicon wafers is coming to an end(a Chinese company is buying every piece of Sumco's equipment that they can get their hands on).
This is where much of the weakness in the state comes from. The state is full of tech workers that can't find a job in their field, too old to go to work for the State(since Salem is also the capitol), and other non-tech employers don't want due to a fear of these employees jumping ship if given a chance. The minimum wage being so high is just as a result of inflation that was started by the tech boom, and now keeps coming around as higher house prices, gas prices, etc; the real problem is that tech is dieing and there's nothing to replace it.
