There is more to it than that. Today’s illegals coming through Mexico (many are not Mexican) are the customers of a large multinational criminal enterprise that sells them entry into the US for a few thousand dollars per head. Every illegal represents another few thousand dollars to the gangster enterprise.
The criminal enterprise does not own the service and therefore has no right to sell it, so it is all done underground. Neither buyer nor seller has any right to participate in the transaction; it is null and void.
Subnormal liberals do not see these simple facts. For the present purpose, let me ask:
Do you see, Mrs. Chavez? Can you see more than a subnormal liberal sees?
