Gated communities sound nice at first, but they are not so safe as the developers say they are, and they don´t have the small suburban shops were your butcher and your pizza/empanada man knows what you like, the local coffee-shop or the local bookstore. And your children will interact with only one class of people, and servants (sorry, house "helpers" and security guards). You still can have the high class connections in the club, without the need to see them or have them whisper about what happens in house X or Y every time you get out to your lawn.
