While true, we have to ask, what is more important? Building the wall, or securing the legal ports of entry? Considering illegal crossings are at a 40-year low and 90%+ of all illegal drugs enter through legal entry points, I'd argue securing legal entry points is a much higher priority. Something else that needs to figure into the calculus is effectiveness. The wall would be very ineffective. In contrast, new scanning technology and more agents stationed at legal ports of entry would likely be more effective than the wall. Cost is also a factor. The wall would cost billions to build, and hundreds of millions, or more to maintain. Trump is asking for $5.7 billion which includes wall funding that would fund 1/4 of the wall, at best. The $1.3 billion offered by the D's and originally agreed to by the R's and Trump before Trump renegged, would include the better tech and money for more agents. Last, other than drugs, what is most important with immigration is labor demand and supply. We have had a demand for immigrant labor for generations. Why are we not allowing labor supply to meet demand in a more efficient, legal manner by expanding our guest worker program? Do that, and how many people are left to cross the border illegally? Add it all up and enhancements to border security at legal entry points makes sense to fight the drug cartels. But the wall isn't worth it. It's a boondoggle waste of money that will only lead to ecological and environmental damage, while not having much of an effect on illegal immigration. Especially since a guest worker program would raise revenue that could fund the security at legal border crossings while lowering the number of illegal border crossings.
