what makes us "Americans" is the ASSIMILATION of various ethnic groups into society.
We are no longer achieving that assimilation,instead we have Balkanization;groups staying separate intentionally. US Hispanics are now using Spanish as their primary language and gov't and private business accommodates them. The muslims are staying separate. the Chinese always have kept their own communities,but now we have Laotians,Vietnamese,Hmong,etc. Then there's the Slavics,Russian,Ukraine,Bulgaria,etc.
