I suspect it may well be much worse. Vox Day is probably foremost among those who predict that America will break into at least three, and probably four, distinct political entities; he's been arguing for a while now that this will happen as soon as the 2030s. I think he's right. Given the abysmal track record of the mestizo and native Central American populations in producing and maintaining stable governments in Latin America, I imagine that Aztlan, however it comes into being, will be a mostly Marxist state. This will likely mean that most of Texas, Arizona, New Mexico, and Southern California will rapidly see economic destitution and political anarchy, of precisely the kind that you describe. It'll be Rhodesia/South Africa all over again, but even worse.

The relatively more free Midwestern states might stave off the insanity for a little while. I doubt that they will resist for long, though. What amazes me, time and again, is how quickly and easily the white population of this country folds before the atavistic and barbarous impulses of the minority races that have done so much to destroy all of the great good that Western society has wrought.
