The problems were SO bad, in the 1950s, that Hollywood even made films about it. And BTW...the smuggling in of illegal aliens, from Europe, right after WW II and well into the '50s, was also so bad, that Hollywood made at least TWO films about that as well; I've seen all of these movies, which I have referred to, BTW. And FWIW, many of the illegal aliens, smuggled in, after WW II, were Nazis and Nazi sympathizer; most of whom have never been caught.
And since "OPERATION WETBACK", nothing has been done by any other president, congress, nor local governments to stop the flow. Reagan granted BLANKET AMNESTY TO ALL ILLEGALS LIVING IN THE USA. You people NEVER mention that either.
You need to learn how to debate, learn more about factual, recent American history, learn some manners, and grow up.
