Sure. Why don't I hear more about Americans doing medical tourism then? Is there some kind of information asymmetry, because it sounds to me as if there ought to be a lot of money to be saved if the sick people knew where they could purchase the medicine they require.

I can sympathize with this because I remember needing a medical procedure that I was forced to travel to a different country to solve, it wasn't even about the money but a case where I the patient was given poor information and then ignored, I actually took the doctor to the board over it in the end, and they ultimately provided a correct solution but it was easier in the end just to travel abroad to fix it.
