Mexican-only open border more efficient and more humane at same time

“Yet some economists and demographers who have studied Mexican immigration suggest that stricter security at the border could actually increase the number of undocumented immigrants in the country. One group of researchers estimates that by 2010, increased border enforcement over the decades had increased the number of unauthorized migrants in this country by 44 percent."

If this is so, then, maybe we should give thought to making the border with Mexico open to Mexicans only. They could move freely back and forth through designated check points — thinning out to the point of manageability all the other illegal immigration which now hides among the movement of millions of undocumented Mexicans. Make things much easier for the border patrol which would be much less inundated with numbers.

Be infinitely more humane for Mexican families too who are now sealed on this side of the border once they get here.
