I say this because it is one of the subjects that will have a direct impact on everyone's life. Every day on TV corporations, government officials, other governments, basically anyone who wields power and resources will vie for people's mind and support. And while doing that they will employ sometimes basic and sometimes sophisticated propaganda techniques. It can thought of a "practical Critical Thinking" or "Practical Logic". Propaganda determines who will be the next president, the next Congressperson, the next State Supreme Court judge.
Great work at a propaganda campaign is what put Obama in power. Ad Age didn't give him Marketing Campaign of the year in 2008 for nothing. He was ahead of Apple and Coke.
Here's an interesting quote from Bernay's Propaganda:
"Different men rule us in the various departments of our lives. There may be one power behind the throne in politics, another in the manipulation of the Federal discount rate..."
I find a lot of people complain about the gap between the rich and the poor, but they never take a second to think about the easily accessible and 0% - 1% interest rate loans that the rich enjoy from governments. Governments creating poverty?!? Nah :)
