I am living in both Paris and the US. It's not what I have experienced.
In Paris, one of my friend has been hit by a motorcycle. The motorcycle run away. She hits the ground and nobody cares. She was disoriented with weird bubble on the skull. I call the french 911, they send the firehouse department who came for finally asking me to go get my car to get her to the hospital. When she can walk, they don't have to take her. I mean WTF?. I took her to the hospital, lot of homeless people, cold waiting room. We wait for 2 hours for her to be taking care of and after that we wait for another 4 hours. The hospital staff were making fun of her because she can't remember her first name and a lot of stuff because of the disorientation (She is pretty so maybe they wanted to take advantage of the situation or something, wtf). Duh? They finally say the scanner didn't revealed anything and send us home. Actually she had blood in her skull and suffer from permanent brain damage now. I mean WTF? Yeah we've paid something like 7 euros I guess, but what's the point if it's for getting treatments from the middle ages?
In opposite, one of my friend got in a car accident in Austin. They wanted to run away, they were DUI but finally get caught. He get to the hospital by an ambulance. Duh? And I finally join him in the hospital. Wahoo, this is day and night. The hospital have scanners or IRMs in every rooms and he has been take of right away. Someone was checking on him every 15 minutes or so. Plenty of devices with computers (duh!) and electronic devices (duh!). And the hospital food was not that bad (for hospital food I mean)! Everything clean and warm, people professional. He didn't get to pay anything because of good coverage.
