There is a good video called "the century of self" out there online that you can watch for free. It's about the brainwashing of society, its evolution from the 1920's through the use of marketing, how the government has been involved, and also tells about Werner's Est and the human potential movements and how they haven't worked, etc. I found it to be very insightful. It tells how most people get involved w/ these techniques as a means to help themselves, and these groups thrive off of people's desires to do so, when really all they are actually doing is getting everyone to conform to rules, and rules to create societies that will follow those rules.
is the link to the documentary page...that particular video is under "anthropology" but there are also a lot of other really interesting videos on there that you can watch for free as well.
Hope this helps.
