Societies have hierarchies: today they are loosely divided into an upperclass, middle-class, lower-class.
Our world used to be more focused on a caste system with royals at the top, religious leaders second (sometimes vice versa), warriors, workers, farmers etc.
What kind of class system could a future society have that is not divided by material matters, but by other matters. Let's imagine that we take our world 100 years into the future with technology expanding at the current rate.
I'm thinking along the lines of administrators, but I am also open to other suggestions.
Edit: in a computer-driven world, the castes might be administrators, programmers, users. But where would the hardware repair guys be, the tech guys, the producers, where would information officers be, where in this hierarchy could you find a police structure observing, even defenders. Because with administrators at the top, you basically override all the other hierarchies. This is basically at the core of any company and it creates quite a messy hierarchy.
