Let's see... for Scholars & Citizens, the careers could be:
(On the Citizen side)
Agriculturalists: primarily rural folks, involved in floraculture (crops and forestry) and/or husbandry (covering domestic and wild animals - hunters would be included in this). While hydroponics can produce more food in a given area, it's expensive compared to farming, and people want "real" food. Despite the best efforts of science and technology, it's people like these who feed the vast majority of the populace.
Labor: the workers in factories and mines, the construction brigades, the blue-collar masses. They don't plan projects, they build them. If it involves making things, these are your people.
Service: the white-collar soldiers in the armies of business. If you're dealing with a company, the odds are good that the face that company wears is one of these people. (Only the tiniest minority of customers get to deal face-to-face with the Big Boss Man - and that usually involves being the Customer Who Can Break the Business.)
(On the Scholar side)
Field Researchers: sometimes, the only way to get the information is to out in the wild and track it down. These are the unsung heroes who do that.
Lab Technicians: sometimes, the only way to get the information is to isolate it and rigorously experiment. These are the unsung heroes who do that.
Intellectuals: whether in an ivory tower or the Groves of Academe, the true lover of knowledge spends untold ages refining the powers of thinking and their products. But always remember: what matters is who publishes first!
Anybody got any other categories?
