Not to worry: if all else fails there are always Indian reservations.
Actually the move in Europe for elective surgery has been towards India itself. Remember the little mini-panic about the superbug a couple of people came back with? India could well develop quite a trade in surgery tourism, if they match USA standards of care.
I have heard that Costa Rica has gained some dental trade this way. I could see lots of US MDs setting up in places like Costa Rica for the future US medical tourist trade.
