It's an economic problem.
Jim, I've thoroughly enjoyed the exchange. The problem is gravely deeper than economics. Every facet of our society is becoming hinged upon the one issue of uncontrolled immigration. Sure, economics play a hugh role, but uncontrolled illegal immigration touches representation, taxation, healthcare, education, and criminal justice. Now which candidate couldn't run an effective campaign based upon cleaning up any or all of those issues?
I'd be willing to cast my lot with anyone who'll listen and at least try. As it is, "It's too big - so we do nothing" attitudes just aren't cutting it. I look at the "choices" and just wag my head in disgust.
No, it's a long-standing cultural problem with Mexico. It’s a culture of intractable corruption which renders their legal system of “payoffs and bribes” wholly incapable of supporting a safe environment for business investment, and free enterprise. And cultural problems don't just suddenly go away; it takes a few generations to change it.
