“As a person’s levels of wealth increase, their feelings of compassion and empathy go down, and their feelings of entitlement, of deservingness, and their ideology of self-interest increases,” he says in his talk from TEDxMarin. Through surveys and studies, Piff and his colleagues have found that wealthier individuals are more likely to moralize greed and self-interest as favorable, less likely to be prosocial, and more likely to cheat and break laws if it behooves them.

On average, households that earned $50,000 to $75,000 gave of 7.6 percent of their income to charity, while those who made make $100,000 or more gave 4.2 percent.

None of the drivers in the least-expensive-car category broke the law. Close to 50 percent of drivers in the most-expensive-car category did, simply ignoring the pedestrian on the side of the road.
