In 2002, I applied for a mortgage in Palm Beach county, FL. I asked the banker what the typical income was for mortgage applicants. He replied with something like "oh, that's easy, $172,400". My income was half that, and I was shocked at his typical figures.
However, when I fly over Palm Beach county, it's clearly chock-a-block full of wealth, very large and impressive homes stretch as far as the eye can see. Over 100 miles of coastline, completely full of significant wealth, from Miami to Stuart.
I'm middle class, yet I live at the outskirts of town, the very West end, backing right up to the everglades, where the cheapest homes are. I'm proud of my lifestyle and my home. However, I'm a stone's throw from poverty.
