The obvious answer to me is that those jobs should pay a living wage for the area that they're in. Minimum wage in the USA is atrocious compared to most of the rest of the west.
Also, those jobs do pay a lot more in the expensive cities. Remember the story of the San Francisco transit janitor who made $270k / year?
