Get rid of anchor babies and they will deport themselves.
They want to collect taxes from their labor, tax all their transactions at Western Union and any other place that they wire money home.

Your solution would work in a conservative world, but It is not going to happen. It is only in a dream that any such thing will break a conservative direction inside of the next few decades.
To make that happen we would have to own the presidency, a filibuster-proof Senate, and the House. And we would have to have all of our side be conservatives instead of “republicans”.
