In terms of access to drugs, the differences between countries is incoherent, not really a "good vs bad" situation. A lot of it has to do with the different ways nations fumble their endless (yet fruitless) attempts to limit abuse and recreational use.

But in terms of cost, the US system is bad. If we as a nation want to invest in drug development, we should do so. Instead we ask grandma and grandpa and the chronically ill to flip the bill. Hard to think of a worse approach.
