The wall is stupid for the most part anyway. It is set up to 500 yards north of the border and would be climbers can be arrested before they even get to the wall, and they are. Most want to be caught anyway to seek asylum. There are many cases where they climb the wall and fall off the other side and are injured and now we have to provide care for them.
I'm not totally against a wall, but it doesn't do anything to solve the real issues we have. So what we spend estimated 20+ billion over 4 years and still have the same problems we have now. Or do we put that 20+ billion into real immigration issues?
Lets also say the wall costs 5 billion a year to construct since it is estimated to take 20 billion over 4 years to complete. Of course it is going to be way more than that over time doing repairs and maintenance.
5 billion a year buys you 50,000 border patrol agents at roughly $100k per year. 50,000 additional agents would be nearly 4x more than we have now. Or maybe some more technology and remote surveillance could be invested in instead. It would take years to add that many agents though. First ya gotta find people willing to do it, not an easy job, in mostly harsh/rough climates. There is a 13 week training course, and you have to be physically and mentally able to do the job.
We also need a shit ton of trained immigration judges to get caught up with the 5+ year backlog of cases.
This is an interesting look at the state of the wall, different types, and terrain issues,
