If I have to guess, what I think you're actually talking about is
1) after middle-class suburban kids leave home to go to college, then
2) graduate and move into gentrifying areas to take internships/jobs in big cities, then
3) get married during that period in their 20s while their income is rising into six figures, and
4) they purchase their starter house in the latest gentrifying neighborhood, then
5) get pregnant and get a dog at the same time, so
6) muggings and property crimes in their new neighborhood turn them extremely reactionary, then
7) they move to a massive palace in the suburbs either shortly before or shortly after the kid pops out.
i.e. the universal American experience.
How is this consistent with #3? $100k incomes are 80th percentile.

All others are renting or not moving into a “massive place” after their initial purchase, which itself was probably barely affordable.
