In "Mr. Mercedes" by Stephen King, the complexity of wealth and generosity is highlighted. Rich individuals often display a capacity for generosity, regardless of their political affiliations or views. However, this generosity is usually limited to their terms and perspectives, suggesting a sense of ownership and control over their charitable actions.

Moreover, beneath the surface of altruism, there exists a deep-seated fear among the wealthy. This fear revolves around the idea that their generosity might be exploited or that others might take advantage of their kindness. The metaphor of someone stealing their gifts and eating their birthday cake conveys the underlying anxiety that accompanies wealth and the sharing of resources.
