How does the author use foreshadowing in Tales of Henry James: The Texts of the Stories, the Author on His Craft, Background and Criticism?

Many of the stories in the collection focus on art or on artists. James clearly sees art as the highest calling, and in The Middle Years, suggests that artistic talent is the source of all wealth. This belief accurately foreshadowed the current shift of the American and European economies to those driven by intellectual property and service industries, rather than manufacturing.
