Department of Psychology, University of California, Berkeley, and Rotman School of Management, University of Toronto conducted seven studies to determine relationship between social class and unethical behavior.
Two studies dealt with unethical behavior while driving. One dealt with unethical decision-making tendencies. One with probability of taking valued goods from others. One dealt with lying during negotiations. One analyzed probability of cheating to increase chances of winning a prize and one with probability of endorsing unethical behavior at work.
The conclusion was the same in all studies – Rich tend to engage in cheating, deception, breaking the law and other unethical behavior more often than people who are not so well off.
