The US can pay doctors as much as it wants. If Americans think that doctors deserve more than they get in other countries, that’s not for me to judge. Mind, that it does imply that the US is more unequal than other countries, because Americans want it to be.
True, merely lowering the administrative overhead will also go some ways to lower costs. But here, too, I wonder if Americans are really willing to do that. Sure, everyone wants to get rid of the useless middle men, but that’s not anyone’s job description.
