Why do you think american writers of subsequent literary periods often choose to break from traditions and seek more freedom in their artistic expression? are writers justified in challenging the artistic status quo? why or why not?

American writers often break from literary tradition because, the audience always wants something new, surprising, unusual, etc. Like anything else on this world Authors change. I believe that writers are justified in challenging the status quo because literacy is an art, and like any kind of art it evolves and changes creating new things. Any attempt to stop change is simply wrong and  insult against creativity.  

Can you provide the statements?
