The difference between other waves of immigration is the fact that in order to survive here, people HAD to learn English. I don't remember my German grandparents telling me that they could vote in German, get government assistance for free(and in German.) The difference in this wave is that there are NO incentives for learning English becauses everything needed to survive is required by government to be in other languages, right up to having translators required where health care is given.
Too much pressure from the top on this issue will ignite a backlash, and soon immigrants will find that native-speaking Americans have gone deaf.
