But that's not what I said above.
A lot of people tend to live in densely populated cities because they like the amenities that come from living where a lot of other people do- like jobs
Jobs are not amenities as you described. It's a necessity and requirement for survival.
The jobs and what they produce is a product of people’s willingness to crowd together into small areas and leave vast swaths of the countryside empty. There is plenty to do and survive on in rural areas, but the pay isn’t as good and doesn’t afford all the luxuries and gizmos that we’ve learned to take for granted.
Wyoming, Nevada, Arizona probably aren’t the best example, just places that you can get a good look at how wide open the country is. There are plenty of other places that are nicer to live and don’t have many people, but don’t make as good a picture to show how empty of people they are.
