I'm afraid that insurance companies are still too powerful and they've had WAY too much say over the health system for far too long. AND it's not just that. There are too many people in the US who have some gut response to the idea of government having any kind of interference in the health system. They scream, "OMG I WON'T GET TO CHOOSE MY DOCTOR111!" But the fact of the matter is, our system does NOT work except for the very wealthy. Even people with great health insurance have problems with the system. I don't have health insurance (except for my overseas insurance that MIGHT cover catastrophic issues), so I don't go to the doctor. I won't go to the doctor unless I'm dying. It's a totally inefficient system and one that absolutely needs to be overhauled.
