This cannot be. The “progressives” (who are the experts on life, the universe, and everything - they tell us so) have told us that the “undocumented workers” benefit the economy. It must be true. Oh, they also told us that there is human-caused global warming. Never mind.
The notion that illegals contribute more to our economy than they cost it has been proved to be nothing more than the spin of the open-borders lobbies. There have been innumerable comprehensive research studies that confirm this. To cite just one, the massive report by Robert Rector of Heritage. His report gives evidence that, if not curtailed, massive illegal immigration could collapse the entire American economic and cultural infrastructure within about twenty years.
