If you go to where Mexico meets the US at the Pacific Ocean you will see a curious thing. There appear to be two fences. One appears to be on each side of the border.
This arrangement is normal and benign. Both countries have their own security needs.
But there’s a journalistic scandal staring at you right in the face. The US media conversation covers the US fence often enough. I can’t seem to find any coverage of the Mexican border fence. Why is it there? How much coverage does it have? How much does it cost to maintain it?
The idea of Mexico paying for its own fence along our common border simply doesn’t enter into the US conversation about borders and relations with Mexico. Omitting it does make for simplified narratives, but mostly that’s in the service of laziness. We could do better, but we don’t.
