They usually have enough money to buy their way out of trouble. Like the head of the International Monetary Fund, being held without bail on charges of rape and forced sodomy on a chambermaid in a New York hotel. Pulled off an Air France jet as it was getting ready to leave New York City, this is going to make a really sleazy "ripped from today's headlines" episode of Law and Order: Special Victims Unit. And Arnold Schwarzenegger--whose separation from Maria Shriver apparently was because she found out that he fathered a child by one of their household staff.
Sexuality is one of the most commonly abused human behaviors, because it is the one that is easiest for people to rationalize or justify. Even the charges against Strauss-Kahn were, I suspect, in his mind just aggressive seduction. A previous victim, described Strauss-Kahn as like a "rutting chimpanzee" when he attacked her during an interview in 2002. (That's sounds worse than Al Gore the "crazed sex poodle," doesn't it?) From what I have read, she was talked into dropping charges at the time because Strauss-Kahn is a prominent socialist (staying in $3000 a night hotel rooms, and buying $35,000 suits). Not surprisingly, French Socialists are outraged at how poor little Strauss-Kahn is being treated. Of course, France is the country that refused to extradite Roman Polanski for drugging, raping, and sodomizing a 13 year old.
One of the strongest arguments against excessive wealth is how many people demonstrate that they lack the character to handle wealth well. One of the strongest arguments against socialism is that its advocates usually end up with a big pile of taxpayer money, one way or the other, demonstrating what hypocrites they are.
