That’s the finding of a group of studies by researchers at the University of California, Berkeley. The research shows that people of higher socioeconomic status are more likely to break traffic laws, lie in negotiations, take valued goods from others, and cheat to increase chances of winning a prize. The resulting paper, “Higher Social Class Predicts Increased Unethical Behavior,” [PDF] was published last year in the Proceedings of the National Academy of Sciences.

As UC Berkeley social psychologist Paul Piff says, the results are statistical and the trend is clear. ”While having money doesn’t necessarily make anybody anything,” Piff told New York magazine,“the rich are way more likely to exhibit characteristics that we would stereotypically associate with, say, assholes.” …
