Looking at this stat and the overall immigration situation, I think things are really going to come to a head in two to three decades. Huge swaths of this country are populated by people who can't speak the main language of this country...(English by the way!) Thanks to satellite tv, cable and 10,000 tv stations catering to every language group, a person can move to this country and never need to learn to speak or write English, increasing the chances of the eventual break up of this country. I can imagine a future where the country breaks up into three or even four semi-autonomous zones, which means that we will end up a third rate world power, because China, which by the way has survived being such a huge colossus because of their imposition of language acquisition on their people, will end up being the Hyper-power eventually.
