This documentary like "Orwell rolls in his grave" exposes how the media is a tool for control of our perceptions. But it focuses more on Fox news. It is probably one of the most important documentaries on the subject you should watch.
This short film is about how a long time American business in Greenville Michigan outsourced it's manufacturing to Mexico. What reasons did the company give? It wasn't government regulation or taxes. It was the fact that they can pay people from Mexico $1.43 an hour.
This film is like a condensed version of "The Century of Self" covering the power of propaganda and advertising in great detail. It also has information that film does not, so I strongly urge you to watch it.
