Gonna need immigration as our society continues to age like Europe, Japan and China to remain competitive. That’s just one aspect.
Did you see the illegals kicking the

out of the NYC cops? LEGAL immigration puts it on applicants to apply at their local U.S. embassy. Their background is checked. Their health is checked. And then they wait in line for their opportunity. They come to the U.S. on the appropriate visa or "green card". They get jobs and live here the required amount of time keeping out of trouble. They have to pass a test demonstrating their knowledge of the U.S. Then they get the privilege of taking an oath and being sworn in as citizens.
Compare that with just letting millions a year come in unchecked. Criminals, terrorists, unhealthy, who knows who. And y'all are cheering this on as if it makes perfect sense.
Do it legal. And if artificial intelligence and robotics develop to the point that a lot of jobs are eliminated what do we do with millions of people we let in along with the millions of our own citizens who are displaced?
