English is spoken over such a huge area of North America that I think it is sometimes understandable that not more Americans are bilingual... in many other places in the world different languages are spoken all around you so it makes sense that people in Europe, for example, would want or need to know the language of those in a neighboring country.

Having said that I do think more Americans should be bilingual... in fact a second language should be taught in school at a very early age.

Speaking more than one language can open so many doors for you. Some jobs take people that can speak more than one language. Plus it is kind of cool to speak a different language.

Being that this is a country of many nationilaties, Yes it would be great to have more people pick up another language. I know Spanish and am trying to pick up Cantonese now. It's beneficial to me in the line of work I am in

Yes. America is not the center of the world, even if plenty of people speak English. We should try to meet them halfway. Additionally, learning another language is enormously beneficial - it improves your linguistic skills overall and changes the way you think for the better. Language is an offshoot of thinking, and more ways of learning to speak/communicate translates to more ways of being to able to think and articulate a position. Bilingualism makes you smarter.
