Does anyone remember a one-off story (Future Shocks?) from an early issue where the world population was so dissatisfied with their lot and it was decided to find the living direct descendant of the first person to invent fire or the wheel which was considered where it all started to go wrong, and execute him? I think there was a twist at the end where it actually it was the world president who turned out to be the true descendant and he was the one who came up with the idea in the first place?
