Mexico had a good thing going. They shipped out their people, money came back in and the US Government looked the other way. But they were too stupid to lay low about it. They crowed about providing assistance, they griped publicly and loudly about any efforts to stop it and called people racists instead of just winking at the friends in DC and keeping quiet. They were arrogant in their disdain for our rules and for the people of the US and they hopefully will get their comeuppance soon.
Now they're finding out Donald Trump has taken political correctness, torn it to shreds, and ground all aspects of p/c under the heel of his custom-made shoes.
