The poster wanted the best public schools for the money. In San Diego, I think that it’s Carmel Valley. That’s why many Chinese families live there for their children. It might become become more diverse over time (a long time).
However, I agree with you, John F, about living in a culurally diverse area. That’s why I want to move out of my homogeneous neighborhood as soon as the time is right.
My Swedish ex-neighbor moved to an old house downtown despite warnings from others. She wanted her two kids to interact with different types of children. She’s not afraid of poor Black and Latino kids. In fact she thinks that it’s good for her kids to be exposed to different people. In the end, I think that her kids will have a great education, in Europe and in America, and perhaps in other parts of the world, learning to get along with all kinds of people. There are certain things that they don’t teach in school.
