Excellent analysis from the Immigration Policy Center. For those fearful of a new wave of workers, just strive to be the best. The best worker does not need the Government to help protect them by preventing otherwise young talented hard working individuals from working. Also, the more people who make money, the more people will spend. Then we all win.
Also, keep in mind that these kids had no choice in coming to America. How would you feel if you were in their situation?
