In "The Witches of Eastwick," John Updike highlights how American culture encourages consumerism by promoting the idea that nearly every emotion or desire can be transformed into a commercial opportunity. This perspective suggests that passion and personal interests are often overshadowed by the need to purchase goods, turning feelings into mere transactions.

This commentary reflects a broader societal trend where materialism is intertwined with identity and self-expression. Instead of nurturing genuine passions or relationships, there is a pervasive belief that fulfillment can be found through buying products, reinforcing a cycle of consumption that defines American life.
