Agreed. But we can encourge them to leave of their own volition by cutting off the welfare freebies and fining illegal-hiring employers. THAT should be the plan. ...along with securing the border with a physical barrier and NG troops of course.
Alas, with the transnationalist commie in the WH, none of that will happen.
I’m thinking that a better plan is to force them to register, collect taxes for them and from them and see how many of them stick around. Right now, an illegal alien nanny makes between $2000 and $4000 per month in So Cal. If the those who employ the nannies had to pay the taxes for the nanny, they would not be able to afford the high wages, then take out withholding taxes and the nannies would disappear. The problem is that the illegal nannies are better than the domestic version.
