5. Los Altos Hills, California (Average Household Income: $405,073)

The town of Los Altos Hills has an incredibly strict commercial ban on operating businesses within its limits. In fact, there are only two retail shops in the entire community: a book store and a gift shop.

Rather than making it a commercial hub, the developers of Los Altos Hills created a space for some of Silicon Valley’s wealthiest. You’ll be hard-pressed to find a better place to relax and slip away from the business world.
