Steve Sailer writes: You are often told that if you look at a map, you can see that it’s a law of nature that the United States of America must fill up with Mexicans. You almost never hear anybody suggest that the map implies that Mexico must fill up with Americans, which would seem more likely a priori.
How do the Mexicans keep the gringos from inundating Mexico? Some of its by law, some of its by violent lawlessness, but a lot is by a sort of passive-aggressive cruddiness: nobody is too sure who owns what land, the streets are dangerous to cross if you aren’t young and nimble, the hospitals are kind of inept, and so forth and so on.
Former foreign secretary Jorge Castaneda suggested that if Mexico were to try to make the country more appealing to American retirees, they’d find they had made the country better for Mexicans. But that idea hasn’t proven popular.
