A mortgage (paying to own property) is the opposite of renting, so Rent Boy’s nickname is appropriate, since he wants to stay renting and never have a mortgage. Although the book often portrays Rent Boy’s choices and particularly his addiction in a morally ambiguous light, in this section Rent Boy defends his lifestyle and his actions, claiming that what he does is better than the alternative (i.e., upholding mainstream ideal). Rent Boy is an unreliable narrator, and so his statements shouldn’t necessarily be taken at face value, but at the same time, the book does explore how Rent Boy might have a point about the emptiness of mainstream society.
