Guest Speaker: Ideology

I find it quite impossible to read a text about our modern world, especially an American work, without feeling it has some connection to the politics and social situation of our country. Since we are living within a capitalist society, and this is true in any such society, capitalist ideals shine through in every type of text written by a member of that society or about those within it.
I do not believe that this forces texts to allow only for capitalist ideals, take for instance, Chris Craig's Jeans example where within a consumerist heaven-a mall-there is an example of socialist/or communist/politics, namely Marx's Communist Manifesto.
Also, we read works of Shakespeare in High School which is a socialist concept in itself-the idea of public schools does not shout out capitalism!
Any text will have to have a position, most have more than one: the position of the characters, of the author, of the reader, of the society, of the government, of the teacher who makes the book required reading. A good novel is one that forces conflict amongst those involved with that particular text. A good author will want the reader to disagree, not only with them but with a character they have created, or possibly all of the characters if a certain idealogy is accepted by them all, or ignored by them all.
Marxist criticism is the one theory that allows for this viewpoint and I believe that unknowingly I have been a Marxist critic my entire life. I feel that all aspects of a text are shaped by influences within the culture or era that particular author lives in...being an author myself I have first hand knowlege of this affect; however, I would like to take it one step further and say that it is possible for some authors to write outside of these influences, or at least outside of some of them, and therefore, they become such an influence themselves on others.
Think about authors who create new styles of literature that afterwards become quite popular and soon others are immitating them-hasn't that author's work become an ideal, absorbed and reused by others? And once this has happened, is the text and the author not an influencing factor of the ideology that other people believe in?
