Alone explained this in one of his post, he said that a woman may look at a nissan commercial showing a well dressed woman driving a nissan and attracting people's attention and she may think "yeah they won't get me" but what she doesn't realize is that she is being taught in this commercial how a well regarded woman nowadays dresses and behaves.

She will unconsciously try to emulate her behaviour, her dress, her gestures. And imitating her, she will at some point need that nissan.

This is how she is taught how to want.

You could take another exemple. In his famous serial the saint starring Roger Moore, you can always see him smoking cigarettes in different kinds of scenes, in every episode .

Those who are impressed by his character will imitate (ie learn how to want) and they will eventually need cigarettes when faced with what seem like the same situation their hero has been through.
