You're implying that both the quality of care and the amount of medical research done is a result of the profits of the medical companies. I'm not sure that this is the case.
Profit is the only thing that drives investment in care and research. You’re asserting that you can reduce profits via price fixing and still deliver the same outcomes in both care and research.
Profit is the only thing that drives investment in care and research
This is manifestly untrue in so many domains, including medicine. Most research is heavily government funded, particularly pure research, and most academics are not interested in profit. The only orgs motivated by profit (drug companies, insurance companies) are the ones who push this misconception, because they profit from it. As one example, the UK runs large trials comstantly to improve care, without a profit motive.
Nobody has to postulate that price fixing (as you call it), or single payer healthcare without insurers works better, because the rest of the developed world outside the US uses that system and delivers very similar outcomes for radically lower cost. The facts are clear.
If you refer to the professionals’ compensations that’s correct, but not that useful as it applies to all of the adult working population.
If you’re referring to the capital accumulation of investments in healthcare companies, you’re off the mark, as there are several examples that falsify your statement, even in the US
