An observation by Steve Sailer, interesting even without its context:
Ironically, when I left the "Collapse" exhibit, with its warnings about overpopulation, at Los Angeles's Natural History museum, I turned out of the parking lot onto Martin Luther King Boulevard, where the billboards were in Spanish. In LA, the African Americans have been pushed off even MLK Blvd. by Latin American immigrants.
I read years back that South Central, the notorious crack-and-gang neighborhood in L.A., was rebranded as South Los Angeles. Not necessarily by some wishful-thinking community organizers, but as recognition that Latinos had moved in and improved the character of the place.
