We just moved out here from South Florida and are still in culture shock over how "White American" it is. It's like moving back to America from a foreign country. I hardly use Portuguese or Spanish anymore and half my family speaks Spanish. The influence must really take hold in South Phoenix. We sure don't see it North of the 101 much.
Our first sign of trouble was going into the local supermarket and asking where the yucca was. Try to buy Guarana and you'll get a blank stare. Still, the quality of people here is so much better than SoFlo, I'm ready to be part of America again.
Funny. My brother moved from Miami to DC because he and his ubber Liberal wife were "sick of feeling like they lived in a foreign country". My family gave Phoenix a shot in 95. It was changing on the west side back then, but there here still fairly defined boundaries. It just started getting too bad around Glendale so we moved back out in 96.
While there recently, we drove all over the west side and it was very depressing. Used to be everything north of Northern was good, with some bad spots south of it.
Sounds like you'd do better at the markets in Paradise Valley or Scottsdale.
