This paper (check ANNEX) places United States on 37th position in terms of medical systems "efficiency" (I cannot tell the date when this study was made).
Efficiency is computed using various factors such as health distribution, financing, responsiveness etc.
This happens in one of the most developed countries in the world (8th place in Human Development Index).
This article tries to grasp the main differences between three developed countries regarding Health Care Systems:
After examining the performance of the German system, we may question whether it is the United States or Germany that has the better system. Surveys of public opinion indicate that Germans by and large are satisfied with their health care system (as opposed to the U.S. where a large portion of the population thinks that system needs substantial changes).
However, this data seems rather old, since it talks about a great number of people without insurance:
The U.S. health care system [...] glaring weakness is exemplified by the fact that more than 42 million people are without health insurance.
This article tells us that the number Americans without health insurance just hit an all-time low:
The percentage of Americans that do not have health insurance now sits at 8.6%, the lowest on record, according to the Centers for Disease Control and Prevention (CDC).
However, this article tells us the plan to the system that created the situation illustrate above.
Question: Considering the US is a highly developed country, why is it so hard to achieve a system that is as efficient as in countries like France, Spain, Austria?
Health systems within these countries seem to be stable for years, so they are a good reference.
[EDIT] Although answers from the duplicate proposal may fit here, this question does not assume that US health system must be a national one in order to make it more "efficient". E.g.: This answer from Quora tells us that "Americans pay 30% to 300% more than Canadians for the identical drug made in New Jersey or California.". Theoretically, better regulation of drugs pricing might increase the cost efficiency of the health system, without changing other aspects.
I am interested in why there seems to be such a difference in the "efficiency" of the health systems between countries having similar economical development.
