That would work, except for the fact that no one will refuse them food stamps, welfare checks, free medical, free schooling, IRS refunds, social security checks, disability payments, charitable gifts, jobs, housing, legal representation, etc.
There isn't a wall on Earth that can stop the third world horde from crashing our borders as long as that carrot remains dangling.
I know what you mean. The only thing is, right now “apprehended” or “arrested” sounds to Americans like it’s a good thing. An recent article proudly said that 750 illegal invaders had been “apprehended”. It later said that almost all of them had to be taken to a (AMERICAN) hospital due to having participated in the “dangerous” trek to the border. I guess this was before taking them to the welfare office. That’s BS. Stop “apprehending” them! You aren’t doing the taxpayers any favors!
