I think if we introduce basic psychology courses into classes, and teach children mindfulness and positive psyschology oriented information, we'll see a great shift towards the goals and behaviors of the generation that grows up with it. These sorts of classes would have a major impact on society at every level, and many current industries would lose out financially, with less people to take advantage of. That won't make them immune to marketing tactics, but it would secure their self-esteem as to not be easily harmed with negative self image advertisements.
