What's stopping US insurers from pressuring drug companies into price agreements? Shouldn't that be also in their best interest, instead of just passing the costs along to the patients? If that's all they are doing, what do you actually need them for?
In Germany, price agreements between drug manufacturers and insurers happen plenty of times, and it usually works out because drug companies take reduced profits over no profits, any time of the day. Patients still have the option to buy the "fancy version", paying out of their own pocket, but the vast majority of patients are completely fine with whatever their insurance covers.
