The DACA discussion in the interview is just more noise but you've made an excellent correlation that deserves to be disseminated.
I love Mexico, I speak Spanish and I go there moderately often - Id go more if it wasnt such a Socialist pit of a state.
I was in Oaxaca a couple of years ago (big drug crime/corruption/teachers union problems) and I saw monuments to the emigrants who had been forced to leave. The state-paid artist made it sound like the US had forced them to leave Mexico or had kidnapped them at night and wouldnt let them come back. But it was simply conditions in Mexico that made them leave.
In truth, Mexicans love living in Mexico and would be back in a second if they had a functional country to go to. Bear in mind that the water in Oaxaca (and most of Mexico and even Mexico City) is not potable. And Mexico cannot even provide its citizens with drinkable water? And they want to know why Mexicans are running away and they want to blame us?
Im hoping Trump will give them a reality check, because weve always just shrugged and ignored the dysfunctionality of our teachers-union controlled, anti-Catholic, socialist neighbor to the south that lets its politicians blame all its hardships on the US. Time to make them become a real country.
BTW, dont forget that Trotsky and many other early Marxists spent time in Mexico and seriously corrupted things there. It has been anti-Christian for a long time, and clergy and religious (such as nuns) were only allowed to appear in public in clerical dress very recently.
