There are no truly homogenously wealthy communities in America

I agree there aren't any homogeneously wealthy areas, because above a certain level of wealth people will have lots of household staff, landscapers, groundskeepers, etc.

However, there are plenty of homogeneously upper middle class homeowner areas.  Think NE suburbs where practically everyone went to college and practically every family has a 6 figure income.

Yeah just to clarify when I say “community” I mean entire county or at least 50k folks if it’s in a denser  area. There are pockets of wealth but ig like I see people pointing all of a County such as Douglas County as wealthy and while yes it has a high median income, “poor” voters are still a large chunk of the electorate.

Several DC area counties have median income >$100K.  They have population >100K and many are contiguous with each other, so it's not just an isolated area.
