The wealthy don't live in Napa Valley, new money does. Totally different thing. Napa Valley is to San Fran what the Hamptons are to New York. IE - the place boringly nouveau riche go to emulate the rich of yesteryear.

The wealthy have their own very large islands. Islands that are very likely nature preserves. They don't need Napa Valley. I can assure you though, that the wealthy also have homes all over the world. And I guarantee you that crappy cities that smell like pee, such as London, San Fran, and Paris, are on their holdings list.

That's just the way it is, cool kids want to hang out with cool kids. And when they're not, they want their privacy.
