Frans de Waal found that capuchin monkeys strongly oppose this phenomenon in an experiment where they were fed cucumbers. In The Spirit Level, Richard Wilkinson and Kate Pickett argued that this phenomenon “gets under the skin,” (10[1])correlating with numerous negative health outcomes. Tony Atkinson’s index of this phenomenon includes a coefficient that represents aversion to this phenomenon. The “central contradiction of capitalism,” (-5[1])which holds that r exceeds g, leads to increasing levels (10[1])of this phenomenon according to Thomas Piketty. The size of two areas of the Lorenz Curve are compared in a measure of this phenomenon, the Gini coefficient. For 10 points, name this phenomenon, the disparity in outcomes between the rich and the poor. (10[1])■END■
