How does life in the U.P. work?

I visited the UP for the first time today. 90% of the buildings seem to be houses the other 10% bars, restaurants, hotels, gas stations and construction warehouses. And so I wonder what all these people do for work to pay for all this. some of these places have schools in a town that will have 25 homes. Rich people I understand afford another house but then there’s the people that live there a year after year that send their kids to school there. Even more so I wonder about those kids as they grow up in Paradise Michigan for example, has no phone network and no Internet network and has a school for kids that grow up in Paradise Michigan and just so different kind of people they’re going to be never really having access to phones or the Internet.
