You were born with the proverbial silver spoon; you have never lacked for wealth. At least compared to the other player characters. Whenever you are in a culture with normal commerce with your home, you have access to lots of money, and can easily buy or hire most things you could ever want.
You are richer than the guy with GreenThumb, but he is more versatile; he can make money anywhere. If you have both Silver Spoon and a Green Thumb, your wealth multiplies and your heirs for several generations will be rich as well.
