Yes, I forgot to mention the Chaldeans also. It is a fact that the Christians that immigrate or come here as refugees tend to start businesses, get jobs and assimilate very well to American life. They are very industrious people, and very friendly too.
That might be a reaction to getting here and realizing:
"Hey, my neighbors aren't trying to murder me, steal all my stuff under law, and rape my womenfolk & children!"
