I believe he means it. I also think he’s really naive on this subject. He should know that over half of the immigrant community is on some kind of social services. He thinks they all ‘work’.
He is not looking at the economics of it. He is not looking at the cultural implications, but they matter a lot.
Immigration is what our country is about. This is not immigration.
I don’t know if he believes that or not. But I also think he means what he says. He was adamant that he would go along with anything until the border was secured.
