Are we ready to talk about illegal immigration in this country yet? It will be a bigger issue in California than any place else. It is not only a Latino problem here. There are huge numbers of illegals from Europe here. Irish, Eastern and Southern Europeans in droves, middle Easterners, Asians and Africans. For example, I do a lot of shopping at a huge local Asian superstore. It used to be a Kmart, tells you how big it is. Most of the check out girls are young Vietnamese. Some of them are still growing like weeds, now that they are on an American, high protein diet. They have bad teeth, are thin as rails and speak almost no English. It's obvious they didn't grow up here and if they had, they'd be aceing their SATs and heading for pre med at UCLA.
Immigrants from all over the World come to SoCal because they have established family ties and jobs waiting for them here. The established immigrant communities here subsidize illegal immigration because they need cheap labor and trust those from their own countries of origin more than others.
Arizona is a big white flight State. A lot of the kids I went to high school with 40+ years ago live there now. They are going to try and choke down illegal immigrants there. Given the kind of White people that live there, I'm sure they will do their best. Multiply the kind of problems they have by about ten and that's what it will be like in California and nobody here really gives a shit about immigrants. Without them, the economy would really tank. Well established White families have been moving out of California for a long time. Along with Arizona, a lot have gone to other Western States, Nevada, Colorado, Utah, Oregon, Washington and Idaho. The thing that makes California different from places in the rust belt, is that the Whites have been replaced by foreign immigrants and the economy has kept chugging along. It has also become an even lower crime area than before and is a very nice place to live. You can't say that about Detroit or Cleveland. Did you know that Beverly Hills is now mostly Iranian? Not a suicide bomber among them. All their children want to keep up with the Kardashians.
I was in San Francisco a few weeks ago and I guarantee you, the immigrant numbers are even greater there, especially in the Chinese community.
You're not going to be able to bus all these people back to Tijuana and consider the job done, nor are their countries of origin going to passively accept them back.
