Because absolute opinions on this are stupid. For every cutting edge cancer treatment we get, there’s another pharma company abusing their position to overprice specific drugs. Since the free market explicitly can’t rectify the situation (patents grant artificial monopolies, sick people have very little option to shop around) there should be some system to review and police the worst abuses. One can argue about whether this type of political review is the best, or if we should have a more structured approach (I would like that, tell Congress.) But just shouting that the current system is perfect and should be unrestricted is also a bad approach.
