Have you ever been into a hospital emergency room on a Saturday or Sunday? Unfortunately, I've had that experience and we have socialized medicine. Its already here. A significant number of people that don't have insurance go to emergency rooms. According to an experienced (read:Gray haired) Infectious Disease doctor I was having a conversation with this week, her estimation is 50% of the people that come to emergency rooms are uninsured.
We in the U.S. spend fantastic sums on health care and our results lag well behind most other developed nations. That's a proven fact. It isn't conjecture. Our system needs repair and it needs it quickly. I think we need to get the system in place that is an umbrella coverage for all and then work on how to weed out the cheats from both the providers and participants. I am under no illusion that there will not be those that try to beat the system but I can't see punishing the majority because of the failings of the few and our fear of rewarding bad behavior.
