This really gets my hackles up, because my kids grew up in schools with a 50% Spanish speaking population and my partner is a dual-language teacher in a district where Spanish, Russian, and I believe Vietnamese are all taught as first-languages in specialized classrooms. Your assertion around English is misguided. This isn't to say that we don't need to get our kids proficient in English (it is the lingua franca after all), but there's more here than meets the eye. In my area we are headed toward universal bilingual education, which I see as only a good thing. That means that it may take longer to reach full proficiency, but the overall outcome is more capable and prepared students.
