I think when one is talking about income disparity and says “lives in a diverse area” you should look at your neighborhood, not a city. How diverse is that? If you walk the streets in a half mile direction from your house, what is the diversity of income, not race, there? I would guess most areas are pretty uniform. This probably applies more to the other thread.
I don’t have many friends I hang out with. I consider my friends my workplace colleagues. And we are probably roughly the same. I’m likely better off than most most are solid middle class by the national definition with household incomes (most with two people working) around $100K. My kids had friends with people less fortunate - with parents in prison or deported - and better off (doctors/lawyers kids). I am “friends” with their parents but I haven’t talked regularly with them since our kids grew up and left. But if we see each other out and about, we stop and chat for awhile like old times.
