The white people (as a race) have had less problems to deal with through the course of history then probably any other race on the face of the earth and therefore probably have the most relatable literature possible. The books and novels are not like ones from other continents where peoples are dealing with racial issues, collapsing governments (or lack thereof), natural disasters, etc. It has always seemed to me that countries outside the US go through much more struggles than us, and so in turn have much more to document in terms of writing. The writing would of course be layered in meanings and come from a voice that has truly undergone struggles.
Don't get me wrong, English Literature is a great thing by far, but I think it's safe to say that much of it is comprised of romance, (aka Jane Austen) drama, mysteries, and science fiction, not personal struggles. It is interesting to hear from another's view how the English Lit has affected the people who aren't English.
