What I meant was that the arguing about it wasn't about the price - it was all about posturing and all that. It's not even really about the issues raised on both sides about immigration.
Yes, there are humanitarian considerations that we should as a nation be considering regarding our neighbors. We should also be considering how demographic changes of any type affect local economies. But if Congress were really serious about the issues, they'd stop being infants and pass the funding resolution then overturn the veto. But no, instead, they are just screwing up the livelihoods of a million (close enough) people.
To continue my ramble...
In a macro sense, immigration (of any sort) is just lost in the general annual population growth. In the micro sense, concentrated immigration has acute effects since the local population change is much higher than you'd get from birthrate/deathrate changes.
The "wall" is, at best, merely an "address the symptom" measure, not anything related to addressing the real micro-impacts of demographic shifts. Don't take my comments to imply I support the wall - I also think it's an unwise approach.
One possible systemic fix to the situation is related to the fact that employment is usually "quantized". What I mean is that, generally speaking, jobs don't change their wages paid in proportion to demand; if you have a company with 100 people and demand drops 5% we don't see all 100 people keep their jobs at 95% pay, we see 95% of the people keep their job at 100% their previous pay. There are many things that are related to this; for instance, 30 year mortgages, or even 1-year rent agreements - basically any long-term financing plan. Health insurance tied to employment, etc.
So I would say we start by looking at things like incentivizing pay changes rather than layoffs and also adjusting finance rules for, say, mortgages, that allow prices to be renegotiated much more frequently and without nonsensical closing costs.
I would gladly take whatever money people want to to put to a wall or anything else and put it to look at that type of systematic change.
