In one of the more surprising findings from their 2015 paper, Keltner and Piff found the rich are more likely to literally take candy from children. In that experiment, they first asked 129 subjects to compare their finances with people who had either more or less money. Then they gave their subjects a jar of candy and told them the sweets were intended for children in a nearby lab but they could take some if they wanted. Those who felt richer after comparing their finances to poorer people took significantly more candy for themselves.
