Some of the best points are blindingly obvious. Will Wilkinson on good peopleracists who advocate apartheid:

Presently, whites are well less than half the Cailfornian population. Hispanics make up just more than a third. Asians at 12 percent are nearly double the black population. I’d guess it won’t be long before Hispanics pass whites to become a plurality.

Now, if my fearful commenters aren’t simply making things up in their paranoid dreams, wouldn’t California be a complete disaster already? Of course, we all know that, were it a country, California would be the fifth or sixth largest economy in the world. The median household income in California, $54,385, ranks 11th in the U.S., and would put California right near the top of the world rankings.

More data: California population born in a non-U.S. jurisdiction: 26.9%, entire U.S.: 11.8% (excluding California should be about 9.8% for the proper comparison).

Some people do think California is a giant burning parking lot, but that isn’t remotely true, even relatively. There are things to dislike about California (e.g., San Francisco is a pathetic parochial town instead of Sanhattan, Scientologists in LA), but approximately none of them have anything to do with the presence of non-U.S. citizens. I’ll take California over Oklahoma (4.2%) any day.
