.Why is Troy so insistent that Cory keeps his job at the A&P?

Distraught, Cory tells Troy that someone else has already gotten his old job at the A&P. Troy tells Cory that he is a “fool…to let somebody take away your job so you can play some football.” The argument between Cory and Troy in this scene also reveals Troy’s deep disappointment with his own sports career. The audience begins to see that this, in part, is one reason Troy is so obstinate about signing a paper for Cory’s scholarship recruitment. Troy wants to think that racism will haunt his son just as, he perceives, it had haunted him. He likes to think that Troy is destined for a similar menial job as he has had to endure.
