Seven studies using experimental and naturalistic methods, reveal that upper-class individuals behave more unethically than lower-class individuals. In studies 1 and 2, upper-class individuals were more likely to break the law while driving, relative to lower-class individuals. In follow-up laboratory studies, upper-class individuals were also more likely to:

exhibit unethical decision-making tendencies (study 3),

take valued goods from others (study 4),

lie in a negotiation (study 5),

cheat to increase their chances of winning a prize (study 6),

and endorse unethical behavior at work (study 7) than were lower-class individuals.

Mediator and moderator data demonstrated that upper-class individuals’ unethical tendencies are accounted for, in part, by their more favorable attitudes toward greed.

"Greed, for lack of a better word, is good. Greed is right. Greed works. Greed clarifies, cuts through, and captures the essence of the evolutionary spirit. Greed, in all of its forms --- greed for life, for money, for love, knowledge --- has marked the upward surge of mankind." ~ Gordon Gekko, 1987

Economics correspondent Paul Solman reports on other new research from the University of California, Berkeley collaborating this, and the impact of wealth on people’s behavior in a new 10-minute video from PBS (posted at YouTube)

This might help explain why some people like Wal-Mart's Christy Walton can rake in $1.2 million a day in unearned income with stock dividends, while at the same time, refusing to pay her employees a living wage in earned hourly income --- costing the taxpayers $6,000 per employee in government entitlements (aka "wage subsidies"). It seems that some of these people just can't help themselves...they're mentally ill!
