I have heard of the horrific abuses that thugs in Mexico visit upon immigrants from the south. It’s basically open season on them - robbery, rape, and murder because Mexico does not protect them.
For 10% of the cost of what we spend on illegals here, they could have a decent life in Mexico.
Deport them all, give Mexico some aid to cover the expenses until their economy improves, with the firm understanding that we will come there and take care of their corruption and drug cartels, if they wont.
Go north the rush is on.
