I wonder what would happen if the U.S. passed a law requiring that drug prices in the U.S. be no higher than anywhere else in the world. That is the drug company is free to set any price, but they cannot sell at a lower price outside the U.S.
Wouldn't it be dramatically easier to just allow Americans to buy their drugs from other first world countries at the prices they pay? If American drug companies have to compete with extra-national pricing, I'm guessing they'll figure out a way to.
On top of that, you're not forcing anybody to do anything.
