Characterizing rural residents as, in any way, ‘hunter-gatherers’ is usually inaccurate. The concept of hunter-gatherer was one that described humans prior to farming activity developing, which, in turn, allowed for settlements instead of nomadic wandering, which, in turn, developed into centers that became, eventually, cities.
Cities were, at one time, central and important to farmers. It is where they went to sell their crops, transact legal business (marriage licenses, deeds, etc…) and to buy goods not available in their villages. Many farmers did, indeed, live in villages for convenience and protection in earlier days.
Today, the average rural resident is not a farmer. Farms get larger and larger and the number of people needed to operate them constantly decreases. No factory worker has ever been as impacted by mechanization and computerization as have been small farmers. But, as some have pointed out, people remain in homes away from population centers for one big reason – it is a lot cheaper to live on some back road than in the city. Most rural residents, these days who have ‘jobs’ have them in towns or cities.
So, why do they continue to live there? Partly cost, but also, by choice. CHOICE. And why do they make that choice? To a degree, because they fear people different from themselves and are afraid they will be at a disadvantage among people used to city life. Why do so many kids go off to college from the boonies then never go back except for funerals and reunions? Education exposes them to the fact that people can live together closely and with obvious religious and ethnic differences without any real negative consequences…indeed, we tend to like it after a short period of adjustment.
To summarize – people live in the boonies because they are afraid to live among people different from themselves. This is a circumstance that pushes rural people to be ever more bigotted in their assessment of city people and city life. They associate liberal goals of opportunity for all, etc., with city people, so they hunker down and take offense every chance they get.
