Indeed.
If I had a magic wand though- and let's go ahead and assume that I don't- I would give trump money for a third of the wall and let his people put it where it is needed most.
And I would then take the rest of the funds and put it into fixing the visa overstay problem which is a complete mess and really where all the action is now and has been for quite a while. And guess what, as the wall tightens, visa overstays rise.
I am not going to do a full flame on it right now because people who follow it know how totally, totally out of control it is and how totally, totally, fixable it is- not 100% - but bigly in a way that reduces the numbers and sends the proper message to the folks back home- don't come. It just boggles the mind how little controls there are over visa overstays and how we have not even applied decades old technology. Every arrival should be coded in and with a scheduled departure date. No entry in the departure field in the database when the date arrives, then -BOOM- it cuts a work order to the locally or nationally contracted bounty hunters or some version of that. Right now the government just shrugs and waits for them to be arrested for something. Not always- so spare me that- but disgustingly so in general.
