It's shocking what can happen to a city over a ten year period. Dallas is turning into a giant barrio. I'd like to move my family farther north, thinking Great Lakes or Dakotas, in ten or so years. And a light goes off over head: "So THIS is how the Balkans happened."
It's what happened to Rome as well. They let in hundreds of thousands of 'barbarians', (foreignors), to work the farms and become soldiers. By the time they were attacked by the the rest of the 'barbarian' world it was too late to defend themselves, they had already been infiltrated and weakened, and the decadence was too much to overcome. History is definately repeating itlself in our own times, in our own country.
