Amnesty's impact on welfare

From Ace of Spades via Breitbart:

An aide to Rubio shrugged off the possibility of millions of American workers being displaced by amnestied foreign ones. "There are American workers who, for lack of a better term, can't cut it," he said. 

So the Rubio plan for these Americans is just to put them on the dole, then? If they can't cut it working, they'll need money from somewhere, and as American citizens, they still have the right to vote themselves wages for not working, right?

Is it that the politicians advocating amnesty don't think two steps ahead. Or do they just assume we're too simple minded to do it for ourselves?
