No, because such social isolation is why the elites in the US and Europe are becoming hated in the West.
They attend the same elite private schools or public schools in posh districts, shop at different stores, eat at different restaurants, watch different shows.
And then the elite holds totally different views than the rest of society and denigrates them for holding different views. The liberal elite making fun of poor whites, calling nationalism evil for Americans but pride for everyone else, bashing skilled labor ...
I intentionally have my children play with families that have very different views, whether a Buddhist family or homeschooling family of 7 with whom we've been in the same youth groups. This is the true diversity that they need to learn to work with, diversity of ideas, not demographic diversity.
