It's not a good idea to repeat that line...well, the 'most' term, perhaps.
Take a look at the criminal damage caused by illegal immigrants and you'll see that there's just no way you can say that. There are too many dead law enforcement officers, full jails, and failing hospitals for that to be true.
My only point was that this problem, despite the best efforts of the open borders lobby, is not going away.
Even if the scale of social benefit programs is curtailed-and I can't envision that occurring, either-there will still be millions of people who want to enter the United States, both legally and illegally.
