Agreed.Illegal immigration problems could be solved easily with two "fences".
First, a real one on the southern border
Second, a virtual one around employers that would restrict illegals from working. (details to be worked out)
No jobs, no magnet
If I were Planetary Commander, I'd make it prohibitively expensive to get caught employing an illegal alien or to give any illegal alien anything remotely resembling a welfare payment.
And any Justice Department officer, ICE official or Federal judge who did anything to undermine that would be put in a canvas bag and thrown off the Tarpeian Rock.
