The physicians and nurses are the public face of the healthcare mess. It's only natural that they would attract ire. You go to the physician and you know they'll overbill you. It's sickening. You get angry the moment you walk through the door.
A couple of years ago I fell for the high-complexity drug testing scam at the intake visit. It goes like this: you pee in a jar, and they send it to an out-of-network lab. A few weeks later the 4.5 kUSD bill arrives, which isn't covered by insurance. Everyone denies responsibility: the physician says you gave us the sample, the insurance says out-of-network, and the lab says services rendered. The charges eventually went away, after several afternoons on the phone.
Civil society offers no solution. It's no surprise that people give way to their anger. There isn't even a contradiction.
