Suffering of the poor may have helped societies with class structures spread across globe
Date:9/28/2011

f socioeconomic inequality have been proposed by scientists, such as a need for hierarchical control over crop irrigation systems, or the compounding of small differences in individual wealth over time through inheritance.

"The fact that unequal societies today vastly outnumber egalitarian societies may not be due to the replacement of the ethic of equality by a more selfish ethic, as originally thought by many researchers," said cultural evolution specialist Deborah Rogers, lead author of the study. "Instead, it appears that the stratified societies simply spread and took over, crowding out the egalitarian populations." The study is a product of her PhD thesis project at Stanford. Feldman was Rogers' adviser.

"This is not just an academic exercise," Rogers said. "Inequalities in socioeconomic status are increasing sharply around the world. Understanding the causes and consequences of inequality and how to reduce it is one of the central challenges of our time."
