“I’m a bond man.”
Nick sells bonds for a living. A bond is a form of debt, issued by either private entities or public governments, and Nick’s participation in this growing field is indicative of the mania for debt that fueled the 1920s boom.
Of course the phrasing here is telling —– Nick is one of few characters in the novel who can form genuine social bonds with others, rather than seeing relationships in terms of dreams, desires, or transactions.
