I don't think giving up on securing the border is the right thing to do either. But doing something super expensive that was tired and didn't work doesn't seem like a good idea. Maybe we could instead try to innovate. Maybe small, autonomous drones that patrol the border might be a approach worth trying. I also heard that they are just lacking the resources to process people who were caught in a timely manner and they ended up staying for years. That sounds worthwhile addressing as well before we spent tons of money on a wall. Or we might even stop the war on drugs which would undermine the Mexican cartels, make Mexico saver and reduce push effects for illegal immigrants.
Penn & Teller did a show on Immigration. Tthey got a bunch of Mexicans to build a wall. And yes, after it was built, they asked the workers to try to get across it.
The wall slowed them down by about 2 minutes. Which isn't really worth it.
Any wall built along the border will likely be similar in efficacy. And even if the wall is perfect, tunnelling under it won't be a problem.
TBH, You'd probably be better off increasing detection along the border. Leave it open, but make sure you catch everyone $21 billion will buy a lot of equipment that can be hidden, and a lot of border patrols.
Walls do work. Not 100% because nothing is, but they absolutely do. Ask Hungary how it's been working out for them: https://en.m.wikipedia.org/wiki/Hungarian_border_barrier
Are you really claiming that's a good comparison to a wall 1000 miles long, through desert and unpopulated areas, which won't* be manned continuously along it's length?
As for the Hungarian border wall, yes, it has helped. But again, EU population density is a lot higher than the southern US desert. It's not just the wall that stops people, it's the frequent patrols, and repairs to the wall.
Given the inability of the US to prevent tunnels between the Mexico / US border, I'm skeptical that a 1000 mile wall will work.
> It's not just the wall that stops people, it's the frequent patrols, and repairs to the wall.
Correct, the wall is but one part of a solution. As far as patrols go, sounds like a fantastic jobs program.
i.e. a way to throw money away doing nothing productive.
Either the people involved will be highly trained / paid well, and therefore bored. Or, they won't be paid well, and will be susceptible to bribes from people wanting to cross.
Note that even Mexico has a GDP of $1.3 trillion (in US dollars), so they can in fact pay for the wall. Even for Mexico, the wall is kind of affordable.
Walls are cheaper than highways. Notice that we have numerous highways running across the USA.
Dealing with these people is costing us 3 to 6 times as much EVERY YEAR as your figure of $21 Billion. If the wall were flawless, we'd get a payback in just 2 to 4 months.
I agree on the detection though. In most areas, the proper physical barrier is probably a fence every half mile for a couple miles, for a total of 5 fences.
It isn't, hasn't been, won't be, and everyone perfectly well knows that.
In 2016 the US spent about $0.75 on CBP for every $1.00 we spent on NASA. Illegal immigration across the border reached new long-term lows, and so did the number of immigrants living in the country illegally. There is no border crisis.
Falsely promoting a crisis is unpatriotic, it undermines the culture and institutions that we collectively refer to as "the country." It's a betrayal, a dereliction of duty.
The point is that the border could be a lot stronger.

The Germans simply flew over it...
Trump does not seem to hesitate offending anyone, so from that point his walls should be more effective...
Would be pretty interesting to see Mexicans reroute to come through canada. I say it in joking, but if you fly to canada and cross over into the US, whats the difference?
