Every day we interact with objects, places and sensations that affect the way we think and feel. This can be used to the writer's advantage by planting symbols in the reader's path to reinforce a specific message, feeling or idea.
Look at the setting and the character's state of mind, and then think about what you want the reader to see. Is there a descriptive symbol or two that works naturally within the scene to help foreshadow an event or theme, or create insight into the character's emotional plight?
Large herds of cattle
*Not all of these are 'true nature', but they would be seen in a more rural setting vs a populated area so I included them here
Private groups and societies
Travel brochures to exotic locals
First class setting
Trendy bars, oyster bars, martini cars
High end clubs
Professional sports teams/players
Merchandise locked behind glass
Resorts, Club Med, etc
Business men and women in power suits
Brand names (Prada, Macy's, Armani, etc)
Downtown monuments, icon landmarks
Expensive shoes or watches
These are just a few examples of things one might associate with Wealth. Some are more powerful than others. A show room of fine sports cars at a Bentley dealership is a strong symbol, and likely will not require reinforcement. However, a gold watch or manicured nails may not foreshadow wealth on their own. Let the story's tone decide if one strong symbol or several smaller ones work the best.
