This article caught my eye yesterday. It's a good read if you want to look it up. I recall Gallagher, one of my favorite comedians from the early 1980s, doing a take-off from Chevy Chase's old news update bit on the first SNL. Almost 30-years ago his joke news item was to announce that the president of Mexico had decided to move his offices to Los Angeles so that he could be closer to his people.
A few years later I stopped over in Los Angeles, spending an extra couple of days to walk-through a visa application in order to visit Australia while on a project assignment. My hotel was just off Hollywood Blvd, around the corner from Grauman's Chinese Theatre. The area was still clean and safe enough, but I could not find a single place to eat where the wait staff could understand English! Not one, in 2-days! Every single waitress was Mexican and not a single one spoke even a smattering of English, or if they did, they wouldn't speak it for me.
More recently, I spent some time in Dallas. It has gotten to be much the same there. Things change, don't they?
