If you are rich, get cancer and can pick any country to get treatment in, which country do you go to? Obviously it would depend on the specific cancer, but I think the US would be the best bet in aggregate.
Well, it depends on what citizenship you have. The point is that if it's expensive in the US now then perhaps in the future it will be cheaper and available elsewhere.
