I recognize that correlation does not prove causation. But here is a picture illustrating the correlation between income inequality and the percent of a country’s population that is obese. The findings are provocative, to say the least.
Making the relationship somewhat plausible is all the evidence we have now of the toll that income inequality takes upon people’s lives. It is one thing to be poor. It is something much worse to be poor when surrounded by wealth. Income inequality increases stress. It is plausible that this stress contributes to behaviors that lead to obesity, and to physiologic changes that predispose people to gaining weight.
