Because I just took an entire class on this topic, I'm going to toss out a little hard data about the US system as it stands.
http://www.commonwealthfund.org/Content/Publications/Chartbooks/2007/May/Multinational-Comparisons-of-Health-Systems-Data--2006.aspxThis report studied healthcare systems in the US, Canada, France, the Netherlands, Germany, Australia, the UK, Japan, and New Zealand.
Of these countries, as far as I can tell from my reading,
only the US lacks some form of universal healthcare coverage. (Detailed information about each of these healthcare systems can be found
here.)
Out of the nine countries discussed in this report, which examined the situation as it stood in 2006 (before any recent reforms):
Healthcare spending in the US was the greatest, at almost twice the per capita, cost-of-living-adjusted cost of its closest competitor.
The US had the most spending on administration and insurance.
The US had the highest spending on pharmaceuticals.
The US had the worst outcomes for respiratory disease, diabetes, circulatory disease, medical and surgical errors. It placed in the bottom half in all but one of the other measures of mortality.
The US had by far the least investment on health information technology, which has been demonstrated to improve efficiency and reduce errors.
Another survey (in PDF form
here)found that more people in the US thought their healthcare system needed fundamental changes or a total overhaul than in any of six other countries from the list above.
So what does all this mean? First, the US healthcare system as it stood (and perhaps still stands, I'm not really addressing recent developments here) is fundamentally broken. Costs are out of control, patient outcomes are mediocre to downright poor, and public satisfaction is dismal. Second, universal healthcare as practiced pretty much everywhere else (note that each of these countries has a different system and a different way of balancing public and private funding) produces comparable or better results at lower cost and in a way that better satisfies their respective populations.
I would say that the US is long overdue to shake up the old system a bit. There are plenty of better examples that we can emulate.
