In an economy like this, even the richest communities across the country are feeling the pain.

Take Southlake, Texas. With an estimated median household income of $172,945, this Dallas suburb is the most affluent neighborhood in the country, mostly due to real estate growth. In 2005, the area doubled its town square shopping center, which bolstered the median household income by over $42,000 since the 2000 census. (Even accounting for inflation, that's still a big bump.)
