I have step-family in France, and I would note they complain about their health care system quite a bit. Two cousins are MDs.
From what I can tell, they have pretty competent doctors in the main.
One issue is that the US market potentiates new drug development, companies know they can get a lot of money here for a new drug, and then sell it elsewhere for a fraction of the cost because the US covers their nut, so to speak.
If you cut out those monies for new drugs from the US, you cut costs, but you likely also cut research into new medications. One thing I learn from TV is just how many medications are now available for maladies I didn't know existed.
