You are correct. We simply cannot mobilize the same resources that we used to bring them all over here in the first place. When we went to Mexico and operated the non-stop bus lines that shipped the illegals into the US, we learned that it was a difficult task. Only when we told them of the great jobs and the social benefits they would get did they agree to get on the US bound transportation.
Since recruited and transported the illegals here, it is now our responsibility to give them citizenship and full social benefits. We cannot punish these people for our actions.
