The specific place I have in mind is in Tennessee. I know there are some nice suburbs in Arizona as well. I'm sure there are more all over the country.
Well yeah it's a tautology that you can't have a significant number of people with 90 %ile schools for example. Fortunately, it seems that a decent number of people like the above poster consider such areas to be "hell", lots of people can't work remote, and the general sense I've gotten is that the nice areas that are more attainable for the upper middle class (high six figure-low seven figure as opposed to mid seven figure homes) tend to be in red states, which acts as a repellent for a lot of the would-be competition.
