“So should we just go ahead and put some bureaucrat in charge of medicine prices?”
Don’t have to. All you have to do is make sure they’re not ripping people off by rigging things in their favor through bribery and other underhanded tactics. Classifying such activity as a form of price-fixing is a solid step. They’ll still rake in craploads of money before the patents expire and lots afterwards. Just not nearly as much.
Care to define what "underhanded tactics" you're talking about, and provide evidence for them?
