Your dog whistle post speaks for itself.
I am continually amazed at folks disdain for undocumented workers and so little for the employers who exploit them.
The solution to the illegal problem is to actually harshly punish employers who employ them AND deport them to the furthest away point from the US possible...so for Mexicans it would be the Yucatan Penninsula. Drop them off on the beach there and wave goodbye. Will take them a long time to walk back to the US from there.
There should be a $100,000 fine for each illegal employed...and have this be actively enforced.
We also have to deny healthcare coverage and all other forms of social welfare for illegals.
No jobs, long distance to travel to return after being caught, no healthcare or other social welfare benefits - Mexicans will be slipping into Canada instead of staying in the US. Our problem is solved.
