This influx of affluent whites has pushed the earlier black and Hispanic groups out into the suburbs. How are white suburbanites responding, if they aren't part of the movement back into cities? They're moving further and further out into the exurbs.
But why? It's not like the earlier white flight, given how low crime is these days. Sure, it's still higher among their new neighbors, and moving further out would bring them into lower-crime areas. But it's not the huge gain that it would've been 30-40 years ago. Particularly if the newcomers are Mexicans, whose crime rates are not even at black levels to begin with.
What about the newcomers' kids fucking up the local schools? That would certainly worry the parents of school-aged children, but would probably not get picked up by the radar of everyone else. It should only be the former group moving out, whereas it seems like everybody is packing up.
Fleeing diversity and its fragmenting effects on trust, in search of greater similarity and cohesion? That's more like it, but why is it the resident whites who are leaving, rather than the non-white newcomers? Is the white suburbanites' homogeneity that easy to perturb toward disintegration?
You wouldn't see that in the other direction, with suburban whites invading and driving out suburban Mexicans — other than by paying more money for rents, goods, and services. The Mexicans aren't going to move out just because they sense a creeping up-tick in the level of diversity with all these white newcomers. They're going to make it known that they aren't going anywhere, and that whites aren't welcome.
And not necessarily in a violent or confrontational way. All it takes is them refusing to learn or speak English, refusing to participate in mainstream American culture, refusing to display American cultural symbols, etc. And then proudly displaying their own.
Whites are a lot more wimpy about asserting their ethnic or cultural identity. I don't mean in some cosplay Nazi style, but in something as simple as playing rock music out of their car windows or on their front porch, walking around the neighborhood, and hanging out in its public spaces — particularly in groups. That would give them a group-y physical presence that would not feel palpable if they kept to themselves indoors most of the time, occasionally going out for a jog alone or walking the dog alone.
To the outgoing go the spoils. If you look around a diverse area today, you'll see that Mexican parents are more willing to let their kids hang out on their own, and that the grown-ups are more likely to be hanging out in the public areas of a shopping center instead of pulling right up in front of their destination, darting in and out, and taking off back home. Even where they may be a numerical minority of private residents, their public physical presence can be much greater.
This line of thinking may also explain why some white suburbs haven't been so thoroughly affected as others. The introverted Scandinavian weenies in Minnesota and Wisconsin have gotten slammed a lot harder by all the black newcomers from the Chicago area over the past 20 years. They're just going to keep moving further and further out.
The working-class suburbs of Boston and New York (who can't just out-bid the non-whites) have fared much better, compared to the rest of the country. You can always rely on the garrulous
Public life is part of the pastoralist culture of honor that the capable defenders are adapted to, whereas retreating into the private domain of the family is more what large-scale agriculture selects for, outside of urban dwellers (and you let the culture of law deal with any problems that may arise). Naturally the Nords are going to have a tougher time driving outsiders back out, compared to the Celts.
