Democrat mayors want their taxpayer subsidized voters.
Republican mayors want their taxpayer subsidized labor force.
The business owners, politicians, governments, shareholders, and finanacial interests want that free flow of cheap labor unimpeded, and will buy, imtimidate, extort, and do anything to make that happen.
Which is why we are where we are at now, a first-world nation rapidly devolving into a third-world fascist shithole.
But hey! Enjoy those record profits (right before the regime kills you, and takes them).
