As an American, I don’t think of the suburbs when I think of rich people. I think of what’s left of our middle class just trying to do their best. Many of them probably have negative net worth when debt is considered. But they need public schools, they need big (relatively) affordable housing, they need strip centers with the same 5 restaurants every exit of the highway. When I think of wealth, I think of mostly inner city old money areas or neighborhoods that have had gentrification (not underway). They live near their work/business, near poverty even, but they don’t commute far because they value their time and they will pay for private schools and create their own sports leagues and stuff for their kids and private security to keep out the riff raff. These areas were probably a far out suburb 50-100 years ago but a city grew around them but their wealth was enough to isolate themselves. That’s where the wealthy people live.
