Joseph Stiglitz, University Professor at Columbia University and a Nobel laureate in Economics: "Health outcomes are also worse in the US than elsewhere for those with higher incomes and insurance coverage. Perhaps this, too, is related to higher inequality than in other advanced countries. Health, we know, is related to stress. Those striving to climb the ladder of success know the consequences of failure. In the US, the rungs of the ladder are farther apart than elsewhere, and the distance from the top to the bottom is greater. That means more anxiety, which translates into poorer health."
