I agree that the world's wealthiest might not be servant leadership, but without witnessing their behavior or learning from testimonies of those who work for them, I don't know if they model the servants heart or not. The characteristics of a servant leader have nothing to do with wealth. For example, I believe Max Dupree was a servant leader and he certainly had wealth. I just wanted to add this idea that servant leadership is revealed from the heart rather than the spreadsheet.
