Go to any community where the average household income is above $200,000 (or a similar number) and look at the property taxes, quality of the schools, how many kids graduate, and what colleges they go to.
We live in a small farm community with an average graduating class size of 80. Yes, there are some families with money but I don’t think the average income is that high.
The parents here are very involved in their kids lives, based on the attendance I see at local sporting events and plays and concerts. The school parking lot is always packed for stuff like that. The teachers also have high expectations from the students both academically and behavior wise, from what I’ve seen from my kids in high school and other parents have told me about.
This public school is regularly sending kids to Harvard, Syracuse University, Clarkson, RIT, RPI, to name a few.
