What if the ad makes you aware of a "problem" that you didn't know you had that they have a product that can address. Think for example an ad reinforces the underlying fear that you are not social enough because you enjoy programming by yourself. It explains that a pill to help "anxiety" is what you need to be healthy or maybe a class to help you become better spoken will change your life for the better.
Many people fail to note that an advertisement often creates or reinforces your fear and sells you the solution to the newly created problem.
That's called psychological manipulation and exploitation.
When you understand and come to terms with the fact that that's what pretty much all ads are doing, it becomes much simpler to view the ads only with disgust and avoid the brands they are peddling in future.
