My own understanding is that American literature has at least three themes that are very distinctive and different from Europe(or other countries). One is the depiction of desolation and human loneliness before the American continent was developed into a prosperous land. Another is the pursuit of the American Dream, where people achieve success through relentless struggle. The third is what this novel expresses: what happens after success? Money and career cannot solve all problems; people need more to fill an entire life.
I think this kind of contradiction is expressed most clearly in American literature and is also most worth articulating within the American cultural context. This is because its commodity economy and social transformation have been too successful, and it lacks the kind of historical entanglements that Europe has to dilute these problems. As a result, this sense of emptiness stands out even more sharply and demands a more urgent response.
I don’t know if there are horror films like this, but I once saw something similar in the TV series WandaVision. She creates an illusion in which she and Vision are a standard middle-class couple, well-fed and well-clothed, with the visuals in black and white. This made it feel like a horror story to me. Why? Because you feel as if they lack nothing, yet they seem like empty shells: their lives are filled with commodities, and all their actions seem stripped of a spiritual dimension.
Of course, I don’t think that America’s secular success means it has no spiritual world; rather, the former has been so successful that the latter has been greatly neglected. The purpose of American literature should be to depict, under the success of this commodity economy, what people’s inner lives have actually become, and what they ought to pursue. This, to me, is its most distinctive quality.
