E.J. Dionne has a great column on the endlessly annoying movement to declare English our 'official language' in some way. I would only re-emphasize that not only is it the case that "the evidence is overwhelming that Spanish speakers and their kids are as aware as anyone of the importance of learning English" but the evidence is also overwhelming that the kids of Spanish speaker do, in fact, learn English and that linguistic assimilation is total in the third generation.
