You may be fallling into the Bush-ite “mass-deportation” rhetorical trap. All illegals would not need to be removed overnight; just start being serious about deportations when they’re caught, and start enforcing employer fines. Start small, so people aren’t shocked, but then keep going resolutely, and raise the fines. I think the word “attrition” has been used for this idea recently, and it’s probably the right approach.
The sum total of this might take 3 or 4 years. It’s not something that has to be done overnight, and doing it gradually is probably the best way.
That is the most sensible solution to the problem.
Definitely I’m for the attrition (self deportation) strategy. The National Review is in favor of it. But the serious criminal aliens will have to be forcibly deported. Employer sanctions won’t impact them. At least most of them
