This one is particularly prickly because the high cost paid in the US funds medical R&D and extremely expensive clinical trials which other countries are free riding on by imposing price controls. We still need to fund the R&D and clinical trials (unless they could be made less expensive somehow), so the most obvious solution would be to have other countries pay their fair share so the US could stop subsidizing everybody else. But that's hard to get.
