6. Kate, Duchess of Cambridge
The glamorous Duchess of Cambridge is thought to have about $10/£7.5 million, and a generous portion of that is probably from her share of her family’s party-planning business. The British economy likely generates more wealth using her image than she personally owns, however. It is estimated she is indirectly responsible for billions of dollars that result from the sales of merchandise that can be associated with her. For example, just one public photo of Kate wearing a particular dress can easily result in a frenzy that ends with that particular dress being sold out in countries all over the world.
