Proof is in the pudding. Europeans live longer, have a healthier life, and a far lower infant mortality rate than do the citizens of the US. They pay only about 1/2 of what we do for their far more successful system. In Taiwan, the overhead cost for their system is 2%. In the US, the direct overhead is 22%. In these nations doctors decide on your treatment. Here, in many of our private insurance systems, the bean counters do. Wonder why the single payer system clients have a longer average life span?
Most single-payer advocates point to life expectancy and infant mortality as evidence that single-payer systems produce better health outcomes than the U.S. And, indeed, the U.S. has lower life expectancy and higher infant mortality than many nations with a single-payer system.
The problem is that life expectancy and infant mortality tell us very little about the quality of a health care system. Life expectancy is determined by a host of factors over which a health care system has little control, such as genetics, crime rate, gross domestic product per capita, diet, sanitation, and literacy rate.
The primary reason is that the U.S. has lower life expectancy is that we are ethnically a far more diverse nation than most other industrialized nations. Factors associated with different ethnic backgrounds -- culture, diet, etc. -- can have a substantial impact on life expectancy.
A good deal of the lower life expectancy rate in the U.S. is accounted for by the difference in life expectancy of African-Americans versus other populations in the United States. Life expectancy for African-Americans is about 72.3 years, while for whites it is about 77.7 years. What accounts for the difference? Numerous scholars have investigated this question. The most prevalent explanations are differences in income and personal risk factors. For example, one study found that about one-third of the difference between white and African-American life expectancies in the United States was accounted for by income; another third was accounted for by personal risk factors such as obesity, blood pressure, alcohol intake, diabetes, cholesterol concentration, and smoking and the final third was due to unexplained factors.
Infant mortality is also impacted by many of the same factors that affect life expectancy -- genetics, GDP per capita, diet, etc. -- all of which are factors beyond the control of a health care system. Another factor that makes U.S. infant mortality rates higher than other nations is that we have far more pregnant women living alone; in other nations pregnant women are more likely to be either be married or living with a partner. Pregnant women in such households are more likely to receive prenatal care than pregnant women living on their own.
Perhaps the biggest drawback of infant mortality is that it is measured too inconsistently across nations to be a useful measure. Under United Nations' guidelines, countries are supposed to count any infant showing any sign of life as a "live birth." While the United States follows that guideline, many other nations do not. For example, Switzerland does not count any infant born measuring less than 12 inches, while France and Belgium do not count any infant born prior to 26 weeks. In short, many other nations exclude many high-risk infants from their infant mortality statistics, making their infant mortality numbers look better than they really are.
In areas where a health care system does have an impact, such as treating disease, the U.S. outperforms single-payer systems. For example, the U.S. has a higher five-year survival rate for victims of heart attacks than Canada, due to the fact that we do more bypass surgeries and angioplasties in the U.S. Hospitals in the U.S. also commit fewer errors than hospitals in countries with single-payer systems like Australia, Canada, New Zealand, and the United Kingdom
