...or wait until Mexico has universal health care...

Don't they already have it?

I was in an auto accident in the Sonora desert back in about 1973 or 74. I was taken to a hospital, got a few stitches put into the top of my head, was kept under observation for an hour or so, and released. My three traveling companions also received whatever medical attention they required.

None of us were charged a penny, even though we were obviously not Mexican citizens and might easily have been seen as "rich Americans." We were, indeed, white Americans who could afford to travel (just barely), and were undoubtedly more affluent than most Mexicans, but we could not have paid for the services we received if the accident had occurred north of the border. Not easily, anyway, and certainly not on the spot.
