What matters in the long run is not the ethnic mix, but how well the immigrants assimilate into the culture, esp. in terms of adopting the language & values. So far we've been fortunate that our immigrants have been motivated to adapt out of self-interest. Actually some of our native-born population needs to achieve fluency in English!

We could have a population as mixed as Brazil's and still be American as ever. And dare I say we have a bit more experience in absorbing waves of immigration than Europe. Having visited several times (UK, France, Spain, Germany, Italy), I reckon it's the EU that could have a problem with rapid demographic changes.
