Census: Metro area rich-poor gap wide

The biggest gap between rich and poor cities in the same metropolitan area? My hometown, Birmingham, Alabama. Mountain Brook -- doesn't the name just say "insufferable rich people"? -- has a per-capita income nearly $100,000 higher than Bessemer -- where I did a lot of my growing up... Overall, there are a lot more poor areas than rich areas in Alabama. And the richest areas are Birmingham suburbs feeding off of the poor city.
