Don't be ridiculous. Governments don't have to bargain with anyone because there isn't consent in the first place. Furthermore, in the past 30, years, big pharma has produced countless miracles, increased the length of life and quality of life for millions, and saved millions of lives. And I am a firm believer in plant medicines—most of the miracles big pharma produces are synthesized or isolated from plants.
I see where you are coming from, though. Although I think that more government involvement will only make the problem worse. Also, compared to the US, Europe is functionally decentralized, which is another reason why single payer would never work in the US. I'm glad you can see how repealing government regulation might fix our healthcare system, though.
