When it becomes universal rule, quite a few immigrants from non-Spanish countries might consider to go back. I know second generation Irish who are considering that.
Is that because they never really thought of themselves as "Americans" or because political and economic conditions where their ancestry came from have improved, while the political and economic conditions for them in the US have gotten worse? My guess is that it is the latter.
My husband and I both consider ourselves absolutely "American" (he is a Vietnam Vet), but we have also considered getting the hell out of the US when we retire -- not to the Balkans for obvious reasons, but if my ancestry came from a country where I spoke the language and felt at home in the culture, I could understand why someone would consider leaving the US for the home of their ancestors. If their families came here for political and economic reasons and then those reasons no longer exist, the lure of "the old country" is a very romantic idea that their parents likely planted in their heads, without necessarily even realizing that they did it.
