Ellen Weis, San Francisco's Museum of Modern Mythology.
Consumerism fuels the capitalist fire. In a capitalist society, the goal is to make money, by whatever means possible, exploiting whichever potential weakness that might exist. The human race is one with a wild imagination, and this wild imagination, though a great strength, can, like all great strengths, serve as a potential weakness.
It is our imaginations that advertising exploits, and it is our imaginations that religion and myth traditionally played the role of satiating, telling stories that have morals to them, lessons to be learned. Now consumerism fulfills this role. The consumer ideology serves as the golden rule, advertising serves as sermons, products serve as our idoltry, and just as religion instills faith at an early age, so too does consumerism.
Ellen Weis (qtd. in "Advertising Characters" 1997) speaks from the perspective of one who is an authority on mythology. Her analogy between religion and consumerism is an accurate one. Undoubtedly, she's referring to this role that consumerism is playing in stimulating our imaginations. It does this by telling us a story, with us playing the lead role, painting a picture of life as being better with the products being sold to us. Our imaginations are carried away by these stories. We want to believe them because they make sense of the world. We want to believe that all it takes to be happy is a trip to the store. This making sense of the world and simplifying to such a triviality is exactly the reason why myths are created.
For example, nearly every cigerette ad features a picture of an ideal person smoking their brand, ideal at least by the standards of most people who long to be accepted. For women, the smoker typically has long blonde hair, a beautiful smile, and perfect, white teeth. The ads that best demonstrates this are those for Virginia Slims. For men you have Marlboro with the infamous "Marlboro man," who is a rugged, handsome loner out in the countryside with his horse and campfire.
