I understand you point and respect it.
There was a McKinsey study done a few years back looking at why the US spends more. One of the interesting facts coming from that report was the consumer only pays out of pocket for about 16% of the heath care they consume, compared to 47% in 1960. The government's share went from about 25% to 50%.
Another thing they found was that private insurance rates reacted inversely to Medicare reimbursement growth. So, as Medicare reimbursements slow, private plans pick up that slack. This is due to multiple things, but a big reason was that inflation attributable to technology needs passed along and the private plans can be adjusted whereas government payments cannot.
If I recall correctly, their other major conclusion was that supply was too high, especially for out-patient care, when compared to the rest of the world. Personally, I am okay with this as it offers up more availability, but that comes with a premium. So, you can reduce availability to shrink costs (i.e., rationing).
I know the US's health metrics do not stack up well compared to other nations. However, I am not convinced that it is due in large part to high costs of medical care. I think we live a different lifestyle, which is unhealthy, and largely ignore our bodies. The libertarian in me believes that those who take care of themselves physically will have the same, or better, psychical life than someone else in a socialized country.
We can better serve our country, IMO, by allowing consumers to see costs of what they are consuming as well as taking an active part in their health. There are ways to incentivize consumers and change behavior without taking away the things that most people enjoy about their healthcare today.
