I feel that literature will always have a place in society, and this is largely due to the fact of how universal it is. It seems weird to think about and was weird to type. Another large factor is the wide variety it brings. Just think of some of the works we went over throughout the class, we had some mystery works, a Shakespeare work, and many in between. In movies and other forms of media there is a limit on the effects or CGI or things of that nature, whereas literature's only limit is the imagination of not only the writer but the reader as well.
I think the book does a great job capturing the battle of self versus the greater good of society. What makes this possible is the common idea of self interests, what do I want, what can I do that is best for me, against what is needed from me to make the world I live in better, or how can I help those around me. One historical example that comes to mind is the Military draft. I feel this example encapsulates this idea perfectly. No one wants to be drafted for fear that they will be killed, but at the same time if you don't go along with it the Military could be overrun and from there who knows what life could be like. So, obviously there were people who put themselves ahead of others and dodged the draft and faced those consequences, but most went with it to keep America what it is. They fought for themselves, but mostly for all of those who were not able to, such as elderly or children.
