I have only been to France twice. About 5 or 6 years ago, I was in Lyon and came down with what I thought was the Flu. I asked at a pharmacy where I could find a doctor. They directed me to a doctor about three blocks away. I waited about an hour before I saw the doctor. He didn't know much English, but he didn't need to. He sent me to an ER where I waited a couple of hours to see a doctor. I had a chest X-ray and they drew some blood. Turned out that I had pneumonia. They gave me two prescription which they filled and I was on my way. Being pretty sick, I can't say it was great experience, but the doctors seem very competent. I do remember I had to fill out a lot of paperwork at the ER, but they had some one there who spoke English to helped me out. I charged everything to my Master Card. The whole thing cost less $500.
I have no idea what the French pay for their healthcare system, but it didn't cost me much.
Also, they asked me for the address of my family doctor in the US. They sent him the results of the lab work which was something I didn't expect.
It is, as I said, a really decent system. In fact, being in Europe, I'd rather get sick in France than the UK. I think (and I'm not saying its a fact - but I doubt I'm far out), that the average cost per taxpayer in Europe is around 25% - That is on top of income tax etc - then they also pay a myriad of other taxes.... Europeans are taxed to hell and back generally.
But.... on healthcare... I'd say as a ballpark it's around 25% of your monthly income on healthcare.... In France - the sicker you are, the better your treatment so don't think you can run to the doc with every little ache or pain.
In the UK, certainly where I live, it can take days to get an appointment with my doctor. The surgery is old and run down, they've only just gone computerized... it's a joke. Seriously.
