To be successful in modern America, you have to carve out a community one way or another. “Carve out” is a fitting verb–as in cutting into an already existing pie and draw what you can from it. The community support which normally would have been taken for granted is no longer there.
The future of America is likely to be dominated by niche ethnic groups, the kind that Amy Chua writes about in The Triple Package. They’ll be able to carve out a good life in the best cities, go to the best universities, and maintain the best jobs. It’ll be a manicured, closed life, though–think business parks and gated communities.
In a lot of ways they’ve already taken over and begun running the country, but the Anglo ethos still mostly remains. Don’t think that it necessarily must though.
While immigration critics often worry about immigration bringing down standards, we rarely mention the affect that many high-quality immigrant groups probably have as well. Unless inculcated into American life, they’re likely to change it forever–especially since they hold all the cards. Let’s hope they’re as nice to us as we were to them.
