We also have to man that wall and rapidly stop anybody scaling it.
I don't see this as an immigration issue. I see this as a security issue. If a thousand Mexicans can cross the border per day, what's the point of checking any cargo at airports or seaports... if someone wanted to bring a nuke into the US, they'd just need to carry it over the border on a pair of horses.
What we need is a chain of tall (>50 ft) concrete towers, with a huge set of infrared/daylight/night vision optics and a 50-cal at the top, as well as a flat-panel directional sound emitter. Have a computer system analyze the heat signatures and warn a monitoring center when anything large approaches the border. If it turns out to be a person, warn them with the long-range speaker. If they move further forward, use the 50-cal. After the first few dozen cases, the attempts will cease. I don't even think we'd need to kill anyone. It would take a total moron to try to run forward if a few 50-cal rounds strike the ground in front of them.
All we'd need are towers every 2-3 miles or so, depending on terrain, to cover the entire length of border. Figure at 5M per tower that'd be $10-20B altogether for initial costs, and then maybe 1-2B/year in maintenance and monitoring costs. Pretty cheap, if you ask me. That's what - $100/person the first year, and like $20/person every subsequent year. ******, I'd pay it.
