"Correction: employer health care costs have risen closer to 60% over the past 10 years while the cumulative inflation rate has been 16.63%. Unsustainable. Especially when we're talking about annual premiums large enough to buy a base model compact car."
Like I've said a few times, I think the answer, at least in the short term, would be for the government to purchase surplus capacity and sell it or give it away.
But I think that the real problem is going to be with the availability of doctors, particularly if the government pursues a course of action that drives down wages. I think that could be mitigated by creating a medical corps similar to what you would see in the military. The government would pay for schooling, provide a stipend, and in return the newly minted doctors would serve for 4-5 years on a government salary that would be much lower than what one could earn in the priavte sector. Once their hitch was up, they could go into private practice, debt free, and make a lot more money.
The other option would be to try and recruit doctors from countries where their pay is typically a lot lower. When I lived in North Dakota, there were many African doctors working there. Because few American doctors wanted to, despite the incredibly high pay they received.
