>that's a massive exaggeration
Lets assume you need to call an ambulance:
Driver (~$100 per hour), paramedic (~$150 per hour) and maybe even a doc (~$200 per hour), their time is about 3 hours to get to you, give immediate treatment, get you in the ambulance, drive you to the hospital and get the paperwork done afterwards.
$900 just to get you in the hospital. Assuming they did give you a slight painkiller, just make it about $1k. The drive itself maybe another $250.
There, you enter the emergency room. Horray, another sum magically enter the bill, just because you had to go here, usually anything in between $100 and $1000.
So the the hospital charges you at least about $1.5k, just for getting there.
If you are lucky and there are no complications, you walk out a couple of hours later, after adding another $1k for X-ray, the cast and another bored doctor, who looked at the results, prescribed a one-week prescription for pain medication and ordered the nurse to get you in the cast.
If you are in bad luck, there are complications and you need surgery, a one-week-stay, more medication and rehab. Congratulation, you long have entered five digits, even if you cut rehab and sell your medication to a junkie.
The health costs in the US are the highest in the world, regardless if you are rich, poor or middle class. And because even the poor think that health insurance is communism, these conditions are not likely to change.
