I see absolutely (positively) no need for bilingual education. Make the kids learn English and English only. If you want additional language education, teach 'em Latin. There are many benefits to learning Latin, including the fact that it will help them learn English, and no one will show up with an advantage/disadavantage because their family does/does not speak it at home. Level playing field.
PRECISELY!
Unless we have -- at a MINIMUM -- a common LANGUAGE (ENGLISH), the drift toward balkanization will lead to a disaster here.
Can you say "Civil War, II?"
