Controlling Governments in Literature

Hi guys!
On Monday for YA Galley Group we are going to be having a discussion on restricting governments in literature. (The Hunger Games, 1984, Anthem, etc.) Some questions to think about are:
1. What are some books that have restricting governments?
2. Do you think that in these societies, a harsh government is needed to maintain order? (We are going to vote on this question)
3. What are the main themes between a lot of these governments?
4. What are some tactics that the government's in these societies use to maintain control?

Also, here is a link to a wiki page that describes different ways that totalitarian governments maintain control over their societies (based on The Hunger Games by Suzanne Collins). If you could read the section under Governmental Control and Oppression for Monday, that would be great! (I know I posted this late so I am also going to bring in copies of the article on Monday.)
