Jay's wish to be a social worker represents a desire to break the cycle of poverty that, the reader will learn, is gripping so many people in Garden Heights and those involved with drugs in particular. This shows that Jay understands that having a mentor figure is one of the most important indicators of whether or not a person will be able to get clean and pursue a more culturally-sanctioned version of success. That she's doing this while her gas is shut off speaks to Jay's sense of responsibility to her community.
