People from wealthy backgrounds are more likely than poorer people to break laws while driving, take lollies from children, and lie for financial gain, a United States study says.
"I was astonished," Dr Piff said. "On average, people in the upper rank condition took two times as much, so it was a pretty sizeable effect."
Also, in that particular study, researchers conditioned some of the subjects first to think of themselves as of a higher social rank by asking them to compare themselves to others with less.
The exercise showed that people could be trained to think more highly of themselves, and that they would in turn act with more greed and less ethicality, demonstrating that status drives greed.
