The funniest thing about this wall is that if it is built, it isn't going to stop a significant amount of illegal immigration.
It'll be nothing more than a $15 billion waste...a permanent monument to the stupidity of conservatives!
It's always been a stupid idea. It is not the wall that stops them, it's guard towers. Walls and fences are just a method of delaying the intrusion. Now if the plan were to put guard towers every hundred yards or so, then that would be effective. Of course 50,000 of them might be considered to be a bit to expensive.
You disbelief in the stone age technology of Walls is pretty funny.
Does that technology include airplanes that fly over them and ladder trucks to breach them, and tunneling rigs to go under them?
Yes.
If illegals are forced to pay for plane tickets, that is a hurdle for them, AND they end up at airports where they have to pass though security.
If Illegals try to drive ladder trucks up to the Wall, getting the truck is an expense AND they might not be taking that truck home, if they get caught.
Tunnels? Digging takes time. Time leads to getting caught. Time reduces flow. Getting caught reduces flow.
