So you brought up two examples that are right next door to each other. I think you are underestimating how big and diverse the US is, as well as the positive impact the tourism and service industry can have. Rich people aren’t the only ones who go on vacation.
You’re right about limited economic opportunity, which comes with its own problems. That doesn’t preclude towns from responsible use of their natural resources or using the tax base to reinvest in the town. Not all do, but some do, to varying degrees of success. This idea that the majority of the US outside of urban areas is in a state of rotting collapse simply isn’t true.
Poverty rates in urbanized vs nonmetro areas are only a few percentage points apart: https://www.ers.usda.gov/topics/rural-economy-population/rur...
