My Cognitive Dissonance about Mexamerica

I'm still trying to work my mind around this pairing:

• Drug violence in the "smuggling belt" of Northern Mexico persists at a level high enough to brand the area as a kind of failed state.  Link.

• Latinos in the United States live on the average two years longer than whites.  Link.

Complicated world.

Update:  Yes, I'm aware that most emigration from Mexico to the US comes from a group of states south of Mexico City, far from the smuggling belt.
