Could this be the problem rising from US having a increased reliance on Allopathic System of Medicine?
In India, Allopathic System exist together with other 4 big system, namely Unani (Old Greek), Chinese, Ayurveda & Homeopath.
Yes, all practitioners have to register themselves to a certain extent with the medical board of India, but the system is not as highly centralized, and is more like professionals working mostly as practitioners, instead of hired workforce.
This can be ironically put as something similar to free market, since the prices are being defined by market forces.
The war over Polio, which India as per WHO has won, would not have been possible if polio vaccine drops were made free, and also their administration, for all people, including upper class.

What I'm sure about is this that if I were to travel to US, to get hurt, and get such a bill, I would go bankrupt over night.
3000$ you can buy Tata Nano!
Also, its worth mentioning, that there is a creed of medical practitioners called "Pehelwaans" (word meaning=wrestler), which is one of the most autonomous individuals around. A stitch for comparison costs around 1$ from them. They appeared out of the sportpersons treating themselves in medieval India, and then making that into community business.
In simple words, compare Pehelwaans with Calculator, very few functions, cheap yet effective in daily life. Both PCs and Calculator exist in real world, same way, Allopathy has been adapted by people for serious stuff, while traditional fields stay prevalent for simple stuff.
Practically speaking, just google how India has become a medical tourism destination, and people from both lower income groups like in Africa, as well as from higher income group from US are coming here.
As of right now, in terms of skill of doctors, US still has the upper hand by far for rare diseases, and everything out of the ordinary. Which is good in one way, but seriously, I'm very disturbed by the fact that 500$ for a few stitches!
heck I could buy a high end phone for that much!
