Cultural Analysis of "What in the World Are They Spraying?"

Below I will be doing a cultural analysis of the text I have chosen, including identifying keywords and how they help to support the author's argument.

For this project I have chosen to focus on the opinionated documentary "What in the World Are They Spraying". The keywords I picked up on while watching were "government", "profit", and "human health". Michael J. Murphy's main argument throughout the text appears to be that the government is involved in a conspiracy theory relating to Chem trails, and that they don't care about the health impacts it would have on the people.

How do these keywords help support the argument the author is making? 

There seems to be a common link between government involvement and the potential to make a profit. Throughout, Murphy continually emphasizes that the government has only taken an interest to make money and that they don't care about the people. By using these keywords, Murphy is more likely to connect to his audience, who cares about matters such as these, and appeal to their emotions.

Why might an audience be more likely to support this argument if it is connected to these values?

By continuing to point out the fact that the government doesn't care about the people and stating the negative health impacts, the audience becomes more invested. In general, the public wishes to preserve their health, and if it seems like the government is going against these wishes there is usually a large backlash. It is also well known that in America the public loathes the government when it seems that they are casting aside the nation's needs in order to focus on making a profit.
