Riiiiight. That's why so many of them start businesses. We all know that entrepenuership has it's roots in socialism. Try again pal. Maybe you should go meet some immigrants before you tell us all about them.
So many of them start businesses because they are able to get loans easy from the federal government. An individual that I know explained to me that he was turned down for a small business loan because he was not a minority, a woman, and not a foreigner. Yes, he's a native-born White American male.
Plus, many of the immigrants work in family businesses, of which ten to fifteen crowd into one house until one business is successful that will allow for further expansion.
