I get shocked whenever I hear some Americans' come out so clearly against learning a foreign language. Mexico, much of central and south America are Spanish speaking, not to mention Spain itself. There is no harm in having your children learn another language in school and it certainly doesn't mean that they'll lose their English. These children will simply be in a better position, no matter what they want to do in life, and so many more doors will be open for them, especially if economic development in Latin America and Spain continues.
In Canada, there are some Anglophones who resent having to learn French. However, it's an important part of Canadian culture and is also spoken by a large variety of people. For top government jobs for instance, it's a requirement to be bilingual.
For example, I speak English, German, Russian, need to work more on my French and am currently learning Arabic.
Is there really a reason to be so strongly against bilingual education? Why deny the children of your state such a great opportunity?
