You can't legalize them. If you reward law breaking, you just get more of it. Reagan's Amnesty was supposed to be for 1 million illegals and it turned out that there were 3 million who took it. Now we have "supposedly" 11 million illegals when we know it's at least double that number. There is no moral reason to legalize them either because we already bring in over 1 million legal permanent residents and over 1 million legal temporary residents each year which is more than every other country in the world combined. They have a legal route, they chose the illegal route.
