Response on movie "The Persuaders"

I was indeed impressed with this movie. When they were talking about politics, especially when they manipulated with words to win voters, I remembered The Declaration of Independence, where Thomas Jefferson in order to gain support to separate from England, originally wrote:"...life, liberty, and the pursuit of property." But a lot of people were poor and did not have any property, so he changed property to happiness, to remove this tension. I think this is when marketing came to existence.
