I think the very first step is to determine what the cost would really be. I think we’re a long way from knowing that. There are a lot of interests to contend with when it comes to healthcare, beginning with the universities’ “rationing doctors” and the nation as a whole doing nothing at all about it, or even thinking about it. Far and away most PCP care could be handled by NPs. Plenty of it is right now, but it’s billed far higher than what the NP gets paid.
I’m not particularly impressed with the French system, though it’s probably better than ours in some ways. But the government pays for medical education and expands or contracts the numbers in medical schools based on the perceived need for doctors.
In France, about 2/3 of medical care is government. You pay up front, then bill the government, which reimburses you about 80 percent for most things. It pays directly for hospital care. About 1/3 of the system (the better third) is private.
