What prevents your characters from making the most of what they have? How do they react to those who may try to take away whatever they have (be it a lot or a little)? In the fictional world you've created, does the government/peoples as a whole make the most of the resources of that world (and what are these)?
If your world is in a stable time, does it ever look back to when it wasn't in that position and try to avoid the things that caused instability before? Has it learned from its mistakes? Have your characters learned from theirs? (I believe one sure way to make the most of what you have is to learn from errors because hopefully that will mean you keep on developing and I think that should apply to your characters too).
