It's unlikely that the people in that rural subdivision are driving two hours a day for work. In the US Midwest, you're rarely more than 30 minutes from a town large enough to have some jobs. For instance, there's a town of 1100 near me that has a veterinarian, general store, post office, gas station, auto mechanic, school, a couple bank branches, and so on, which all employ people, some at pretty good salaries. And within ten miles of that town, there are a couple of those little blocks of suburb-looking houses like you describe.

Or the people living in them might be retired, or work from home, or work on local farms. Whatever the case, they're not driving a long way for work.
