There have been places where German or French or Spanish or Italian or Vietnamese or Chinese or whatever have been used exclusively in the US for pretty much as long as the US has existed.
And you know what? It's not really a problem. People who want to do more than live in their little corner of their little town will learn English. Some others won't and their opportunities, as a consequence, will likely be limited.
Again, I just don't agree with this. I think non-English speaking groups are expanding enough that there is plenty of opportunity out there without knowing English. No, you wont get to be an officer in an English speaking US company but the Latino community is having big success in all aspects of American life. It's just a matter of time until there is a Latino facebook/google/whatever and then you'll have that opportunity too.
Personally I think it's great since I view the fact so many Americans never have to learn or even really be exposed to any other language is a big disadvantage.
If you look at Facebook and Google's popularity throughout the world, I think it's obvious that language isn't really a barrier to their spread and popularity, outside of some Asian countries where politics are also a factor.
I guess I'm just not scared of there being people speaking Spanish in the US. Over time, they'll integrate, just like everyone else has in the past.
