It's fine to look at the causes of those deaths and blame the country, its citizens, politicians, or whatever. But, it's not the fault of an insurance company, hospital or doctor. Better access to health care or more medical research will not prevent those causes of death. Those causes of death are irrelevant to the argument. On the other hand, smoking and diet are relevant to the quality of a health care system, since they both lead to chronic conditions and the victims of the related diseases will require medical care. Medical research, doctor knowledge, access to care will all play a part in how long that individual lives.
Anyway, we’re just arguing in circles While I agree a country's life expectancy has it's place, it is not necessarily a reflection on the qulity of a country's health care system, at least not until you remove causes of death that a better doctor, etc will not have any affect on. And a better doctor is not going to be able to save someone that died on scene in a car accident or murder.
