The Melting Pot is Broken - It's a particular problem with Hispanic immigrants:

The Mexican invasion is significantly different from immigrants of the past in that generation after generation is failing to assimilate into our language and culture. The illegals retain their loyalty to Mexico, not the US and thus are a major security problem during demonstrations such as those protesting the Arizona enforcement law.
