We are indoctrinated without ever having considered the issues. When an advertising agent approaches a new product often the very need for the product must be created in the public's mind. If you can create the belief that the new product is needed, it is guaranteed to sell. Without exciting the desire for these products the wheels of the economy would stop turning. Advertising has been the most effective tool used by the world's power base to control the population.
Advertising provides the carrot on the stick that keeps the beasts of burden trudging forward.
In a land of plenty such as the United States, to persuade an entire population to spend the best part of their time and energy in labor is an amazing feat of coercion. One of the reasons capitalism has succeeded while communism has failed is because communism used force to control the population, while the capitalists have brilliantly brainwashed the population into doing what they are told while making them believe they are free. It is a master job of social control that keeps the economy moving and the rich powerful and free. One of the main tools used in achieving this amazing feat is the national media. Those in power have been effectively using the media ever since it emerged, and in their hands it has defined our values as much as religions did even previous ages.
