Popular author J. K. Rowling, who was once poor, has earned a fortune with her Harry Potter books. Rowling is now a member of the upper-middle class.
Though J. K. Rowling has made a fortune for herself from her Harry Potter series and moves, she started out on the very bottom. Most people in the upper-upper class have been wealthy from generations to generations and it is passed down. Though members of that class can earn it on their own, they are typically people in power over major decisions. Rowling is above the middle class as income goes and falls right in the upper-middle class category.
