The slot is a metaphor of the "class cleavage of society". There was a contrast between the North and South of the Slot in terms of building types: in the North were the higher-class centers of diversion, lodging, and business; and in the South were the lower-class centers of lodging, unskilled work/business. The buildings are figures of two contrasting classes that were segregated (?).

He finds himself working as a fruit-distributor among the women and decides not to change their work conditions. In six months, Drummond works at many jobs, and succeeds in imitating a genuine worker. As FD makes tentative generalizations about the working class, he is applauded by the business people, who divulge and spread his studies to the working class.

He changes his values and attitudes as easily as he changes different types of dress. Social class also shapes his relationships. He conforms to the expectations of the two contrasting classes. He adopts the typical vices and virtues of either class. His food choices, behavior toward women, and character are shaped by the two
