There will never be a secure border because the worst of it comes in aboard jet liners, and walk the red carpet.
I was hit by an unlicensed illegal who totaled my car in 1992.
They deported him ( again) and he was back (again, and working for the same company) inside of two weeks. He didn't have the money to be flying in.
The problem with dishonest lying little weasels like you Editor-Surveyor is that you can't stop the people these illegals hurt from posting on forums. There are millions of illegals and they do a lot of crap to a lot of people.
My wife and infant child were in the car. Excuse me. My “low information wife and gang child” to classify them as Editor-Surveyor sees them. We were stuck at the back of a line of cars waiting in a left turn lane when a speeding Pickup swerved into the side of the little Taurus I was driving.
The guy couldn't speak English, had no license, no insurance, and no remorse.
Just one of your special pals Editor-Surveyor.
The day laborers are not our big problem; we can eliminate them with enforcement of the laws against employing them.
The worst of our problem is coming from across oceans.
