Finland and Japan, just as two examples, provide strong evidence to contradict this incredibly broad assertion. http://en.wikipedia.org/wiki/Healthcare_in_Finland

It would be just as untrue for RJ to say "One thing the US has proven conclusively over the past sixty years is that the private sector cannot efficiently provide health care". It is true that the US system does not, by any stretch of the imagination, efficiently provide health care, but it is a vast leap to extrapolate that to the conclusion that it is impossible for an efficient private health care system to exist, which is what you are doing in your claim about government-run healthcare.
The sentence in bold was actually loosely quoted from an article in The Telegraph describing the problems with the NHS. But you're right. I'll restate it as follows: One thing the NHS has proven conclusively in its sixty some years of existence is that the British government cannot efficiently provide health care.
And my main point remains the same. America should not put in place an NHS-like system here.
