DANGERS OF HIERARCHY IN HEALTH
"To understand this factor, we need to recognize that the health of the US population is disgracefully poor compared with that of other rich countries. In the ranking of countries by life expectancy in 1997, the United States stood 25th, behind all the other rich countries and even a few poor ones.2 The country that has won the gold medal in this health Olympics every year since 1977, Japan, is also tied for the gold medal in the smoking Olympics. That is, the prevalence of smoking in Japan is tied with that in China as the highest in the world and 3 times that of the United States; yet, the Japanese do not die of smoking-related diseases to the extent that Americans do. Lung cancer mortality rates in Japan are one half to one third of those in the United States. How does Japan do it?
The answer is simple. The health of populations in rich countries is determined primarily not by the health care system - we have the most sophisticated and expensive, so it cannot be that-or by individual risk factors such as smoking, but rather, by the gap between the rich and the poor.
Many recent studies show that populations with a greater income hierarchy are less healthy, and specifically have shorter lives, than populations that are more equitable.3 These studies have looked at mortality and income distributions among countries, within countries such as each of the 50 US states, and within 282 standard metropolitan areas (US cities).
They have also looked at homicide rates, teen births, and specific diseases. Independent investigators have studied many different populations using different methods, and all agree: the strongest factor affecting health is the size of the gap between the rich and poor.
Other studies suggest physiologic mechanisms through which greater hierarchy results in worse health and posit that humans are by nature egalitarian.4,5,6 The analysis has the same level of validity as the relationship between smoking and lung cancer, using the criteria postulated in this country by the Surgeon General’s report in 1964.
