In America there seems to be this hero worship of anyone who is wealthy, that somehow it makes them better people and harder working than everyone else. I would say a good chunk(not all of course) of them are just more willing to do whatever shady shit it takes to be "successful". Usually the higher up the food chain the more ruthless they are. I remember the president of the US offices of my company telling me it's not what they know it's what they can prove, even though we turned him in for outright embezzlement the company didn't press charges and let him go with a golden parachute because he had dirt on the CEO. Ah the American dream.
