While I can fully agree that a lot of the costing that happens in health care is opaque and quite high, the idea that opening up the system to a non insured model would fix it all is hopelessly optimistic and wishful thinking based on ideology rather than fact. I quite sure that no involved parties would advocate even an attempt at this concept.
Health care billing is already impossibly complex to comprehend, even for the experts. What is the overhead on an OR that goes unused for 12 hours a day? How many different doctors, nurses, anesthesiologists, medications, blood, etc are needed for an operation? When they open you up an find a tumor they weren’t expecting do you want them to close you back up because that wasn’t part of the procedure?
A VASTLY better and commonly used system throughout the rest of the world is to have an entity charged with regulating and controlling costs for the industry. While we know it as socialized medicine here, it is not about that. It’s about a single point of cost control. That is why all these other countries that offer care superior to ours by just about every metric yet operate at half the cost. Most are not perfect systems. No large multi player market is. However, you cannot argue with the results versus our own.
