Ten Percent of Wall Street Bank Workers are Psychopaths

Ten percent of people working for Wall Street Banks are psychopaths.  On average, only one in a hundred people are psychopaths.  The psychopaths working on Wall Street do not mind taking on a lot of risk in their lives.  They are normally outgoing, charming, and smart.  These traits allow them to hide their destructive habits when they present themseves as the perfect employee at any of these banks.  When they take on huge risks, they will do everything they can to make their bets pay off, including those made with other people's money.  This includes taking on huge amount debt, embezzlement, and fraud.  They justify trying to redefine the rules, so that they can engage in behaviors that normal people would consider corruption.
