In some of the comments to earlier posts, I see some indications that some commenters believe that if immigrants come into the country, they are going to pull right up and move next door. This is extremely unlikely. And even more unlikely in the red states where a lot of immigrant haters exist, even though those areas have very limited immigrants.
It must be understood that immigration has next to nothing to do with who lives around you. As I have explained before, I live in San Francisco, which is one of the most diverse cities in the United States. In the downtown financial district, you see whites, Asians, Latinos, Indians and blacks. But at the end of the day, they all pretty much go back to their own part of town.
I live in a predominately white neighborhood, with a few Asians around. As a matter of fact, now that I think about it for the first time, the 40 apartment complex I live in is, I think, all white.
I have only a rough idea of where the Filipinos or the Mexicans live. They go to their own neighborhoods at night. It is the same in every city.
There is a large Korean community in LA, a Jewish community, a Persian community, a black community, an Ethiopian community, etc.. Some mix during the day but most go back to their own neighborhoods at night.
Some people like to mix, most like to be with their own. In other cases, some may want to mix based on where they are on the social ladder. Up and coming millennials may want to live in the same neighborhoods, regardless of race. The same for top corporate executives.
So if new immigrants from Haiti or Norway were to enter the US, they are going to, for the most part, find their own communities and not move into our settled neighborhoods. It's a ridiculous idea to think they will en masse. (Though a given neighborhood can change over time, the same way gentrification can make a neighborhood more white.)
