From the right-wing Washington Examiner:
If Trump wants to reduce illegal immigration (already at an all-time low), the best thing he can do is to encourage our neighbors to the South to continue embracing free trade and commerce that has been empirically proven to raise the standard of living, create jobs, and lift millions out of poverty. To the extent we are able, we should be encouraging increased economic opportunities for Mexicans in Mexico. This will result in even less migration.
If Trump thinks Mexico is bad now, just wait until our neighbors to the South turn their back on the free enterprise system.
