What are the lives of the planet's wealthiest people really like?
Several years ago, sociologist Brooke Harrington decided to find out.
She knew she'd have a hard time gaining access to the world of the über wealthy, so she did something unusual: She took courses to become a wealth manager.
In the course of this training, Harrington met other wealth managers, who agreed to be interviewed for her research.
She discovered that, in order to manage money for the super-rich, these professionals learn a lot about the private lives of their clients.
