Do you have class systems in your world? Can they answer these questions?
1. What determines wealth and status in this system? Is it based around how much land you own, lineage, or something more complex?
2. Who is on the top of the system? Who benefits? Nobility born to rights and privileges? Business success? Being the child of someone with business success? Who benefits from high status and wealth?
3. Who are the poor? Those that don’t benefit from wealth or status?
4. Is there a middle class that might not have strong feelings for the system and are fine with it despite possible sympathy for lower classes? Or merely seek to gain status for themselves? This is something rarely seen in class systems for fear of that dreaded nuance.
5. Class systems are usually in at least a little flux. What changes, however small, are happening? If not, why is that?
