Dramatic differences in health are not a simple matter of rich and poor; poverty alone doesn't drive ill health, but inequality does. Indeed, suicide, heart disease, lung disease, obesity, and diabetes, for example, are all linked to social disadvantage. In every country, people at relative social disadvantage suffer health disadvantage and shorter lives. Within countries, the higher the social status of individuals, the better their health. These health inequalities defy the usual explanations. Conventional approaches to improving health have emphasized access to technical solutions and changes in the behavior of individuals, but these methods only go so far. What really makes a difference is creating the conditions for people to have control over their lives, to have the power to live as they want. Empowerment is the key to reducing health inequality and thereby improving the health of everyone. Marmot emphasizes that the rate of illness of a society as a whole determines how well it functions; the greater the health inequity, the greater the dysfunction.
