The suburbs I've lived in have been both age-diverse and culturally diverse, but they tend to not be income or "status" diverse. You don't have a lot of poor artists in your neighborhood, for example. The main problem is the design, not the people. The design makes it much, much more difficult to have spontaneous interactions with those in your neighborhood because you aren't walking around in your neighborhood because there's nothing to look at and aimless walking isn't very popular and so you just drive a car to the grocery store where you maintain anonymity and you can't even get to know the workers there because they're transient (many good/bad reasons for this). Additionally there is a cultural stigma around what amounts to being too friendly with your neighbors and that general pervades the suburban landscape. Obviously not everyone is like that, nor are all suburban neighborhoods the same, but as someone who has family members like this and has grown up around it and now lives in a walkable neighborhood it's striking how clear and obvious it is to me. I live in Columbus. My brother says "can't do it there are too many people on the streets and sidewalks". That's the lived experience for many Americans who reside in the suburbs and it is specifically chosen to live that way to avoid other people and instead stay inside most of the time. That's why the houses are so large and why there are pools and things. The point is to not go outside of your house or engage in a risky exchange with your neighbor.
