Capitalism, which ceases to exist if it is not expanding its empire, establishes an ever-moving frontier, and its yang conquistadors forever pursue El Dorado. You cannot be too rich, they cry. My realistic fictions are mostly about people on the yin side of capitalism: housewives, waitresses, librarians, keepers of dismal little motels. The people who live, you might say, on the rez, in the broken world the conquistadors leave behind.
