Knowing how advertising and propaganda works does not mean you can actually use these tools in real life, especially on the level that most people interact socially. Once one in a thousand people understand the mind games which are very common today, we are not going to see a wide scale revolution, because very few people have access to millions of dollars for advertising. instead, I would expect the information to just start leaking to their friends, and before long become common knowledge even to those who never heard of the course.
