This is exactly why I get so pissed about the Affordable Care Act! We are not solving the problem of why medical care in USA is so outrageously expensive, we instead are solving the problem of how to pay for it. The problem is, once most people have insurance, there will be no political will to solve the much more complex and important problem of reducing the healthcare costs for everyone.
Incidentally, totally agree. In any hospital, all you have to do is dispute the charges and demand documentation, and all of the sudden the bill is slashed tenfold! So, basically, the system is setup to screw the uninsured americans who may not know their rights or have the ability to challenge the hospital.
