could it be that other countries just limit the amount of care you get? I went to a Dr and asked about treatments done overseas. (surgery here vs months of different other treatments there). The answer was that it would take 9+ months to get the surgery overseas, so people have to suffer for months before even getting the option to get treatment that will work quickly.
I've lived in the USA, Europe and South America and although that can be true it's not as bad as some make it seem. Friend who had hip surgery for example got a date that was several months out to replace her artificial hip. I guess that needs to get done a few times so it's not life threatening. Either way for emergency procedures they don't make you wait. So your example really would require more specifics. It will depend on what you want done. I have no idea if there's a wait for an artificial hip in the USA so even I can't make a proper comparison.
On the flip side you can leave the USA to get dental, cosmetic, or other treatments in other countries for much lower costs at the same or even better quality.
I'm not advocating a perfect system. That's a tough thing to ask for considering how much longer we live, how advanced some medical procedures are, and how convoluted it must be dealing with all the players. However lets at least face a sobering reality. It's too expensive in the USA and we are pretty much ranked dead last when they factor in availablity, quality, and cost. We're 34th for life expectency and infant mortality, we're the only country with no universal coverage in the developed world, we spend 20% of our GDP on healthcare, and nearly 2 million people go bankrupt every year due to medical bills.
Probably worth noting that both countries I have lived in outside of the USA have had healthcare systems that are ranked higher than the USA according to the World Health Organization. The USA is ranked 37. I would agree with them. For reference that puts the USA behind countries like Saudi Arabia and Cyprus. Embaressing.
