In this case the girl was abandoned by her father and her mother couldn't look after her because she had to work so her daughter had to be brought up by relatives. Also, she is described as dark so perhaps dark skinned which would make her a target for racism if say in Canada or the US. Dr Gabor Mate, a medical doctor in the downtown eastside of Vancouver, BC Canada says that, for example, drug addicts have most often had a terrible upbringing so they have sought relief from the emotional and physical pain with narcotics. For example, one baby was kept in the dryer with a weight on the lid while his mom went to bars to pick up men.

McKay personifies America as a woman who feeds him "bread and bitterness" and who sinks her "tiger's tooth" into his throat. By using the pronouns she and her to refer to America, McKay turns the concept of a country into a person who can cause the narrator harm even while he loves her. The effect of this personification turns the relationship between the narrator and his country into a more personal relationship, full of the conflicting emotions that come along with loving a person.
