When I look at all the statistics via the links and within this debate, I am unable to draw any conclusions. There are too many variables between countries such as level of health care desired (demand variables), cost to individuals via various programs (supply variables), and other factors such as how much time it takes to receive health care(demand variable), which are not listed at all.
It would be better to compare health care delivery systems within a population to compare systems. If one person is exposed to various systems and give a testimonial, this would mean more to me, though even this could hide factors such as cost.
Mrs. Pigpen's testimonial on Tricare is valuable due to her personal exposure to various health care systems.
I only have my life experiences to compare health care. I am not impressed with our health care system compared to other services. I have no direct contact with National Health Care system within our country. Indirectly, my father will not touch his Veteran Health Benefits with a ten foot pole. I see the effect of government health care programs on health businesses I contact and it does not look good. Health care is slow, inefficient, poor at educating its clients so they can make practical decisions, and more concerned with appearances than providing cost effect medical care. How much of this can be attributed to National Health Care system is debateable. I believe it is contributing to "unnecessary crap" to quote a famous American.
Perhaps someone can use the statistics to show evidence National Health Care system are working well but so far I have not seen it. I guess I can not show evidence it is failing, either. All I can offer is my empirical observations.
Some interesting evidence to look at would be the cost of health care for animals versus humans. Health cost for animals is much less than for humans for similar services. That evidence shows the efficiency and cost for animals is much better by a wide margin. Life expectancy for pets is on the increase. Perhaps comparing the health delivery system for animals versus National Health Care might contain some of the evidence being sought.
