The healthcare industry has been thoroughly regulatory captured, so profits generally represent steeper zero-sum wealth extraction rather than having provided mutually consensual transactions. We likely agree that the main dysfunction of the healthcare industry is the complete lack of price signals, but without multiple key dynamics being fixed (off the top of my head: the nonsensical ability to create post-facto bills not based on any contract, anti-competitive arrangement between "insurance" and "providers" in the form of price fixing "networks", lack of statutory maximum rates for emergency care), superficial deregulation would only make the problem worse.
