1. I doubt the effect of this is as strong as you seem to think, but ok.
2. There's a reluctance to allow doctors educated elsewhere to practice without undergoing a rigorous accreditation process of some sort in nearly every country in the world except possibly in some of the most destitute third world countries. This isn't unique to the US.
3. All over the world doctors have to train for at least 8 years or so before they can practice. Again, not unique to the US.
4. There's a reason for that. It means the worst quackery is kept off the market. I'd say that's a good thing (also, it's not unique to the US, although the FDA is indeed a world leader in its stringency). Note, however, that the entire world is using (and paying for!) drugs that have been through the rigorous FDA testing process, so again this is not a reason why medical care in the US is more expensive than in the rest of the world.
