In the last parts of The Death of a Salesman, Willy has just lost his job but still is excited about the fact he gets to go out for a fancy dinner with his sons who he believes have been successful and everything will be alright. When Mr. Wagner leaves, Willy slips into another memory in which Ben offered him a job to come to Alaska with him but Linda tells him Willy is on track to become a member of the firm so he can't take it. Ben also asks him whats important and Willy says it's not about what you do, but how well liked you are by people. This reiterates Willy's character and personality in the fact that you get success from being well liked while in contrast Ben is all about the fact that success is about wealth and physical things you can touch like money. In a new memory, Bernard enters as the Loman family is about to go to the football game and Willy has very excessive expectations in the game. This memory in the plot shows that Willy and his priorities are mixed up because he believes that Biff's success on the football field is more important than anything he does in the classroom. Now in the present, Willy goes to Charley's office and there stands Bernard all grown up. Bernard is highly successful and going to Washington to argue a case in the Supreme Court but Willy, through all is memories, is unable to understand why Bernard became successful while Biff has never lived up to his potential. I believe the reason Biff failed was because of the values Willy instilled in him while Bernard is successful because of the values Charley instilled in him, those of being a careful and hard worker. Willy asks Bernard why Biff was never successful and both agree that Biff's life derailed after he failed math which is because Willy told him that football and popularity was important while school was not.  Bernard recalls that Biff was determined to go to summer school because he wanted to rededicate himself and really work for success but after going to visit his father in Boston he comes up and has given up so whatever happened in Boston was crucial. Willy refuses to discuss what happened, so whatever did happened was important and was a huge factor in the failure of Biff. Bernard leaves and Willy goes in Charley's office, Charley starts to count the usual fifty dollars that Willy usually asks for. Willy selfishly asks for a hundred and ten dollars because of all of his payments due and Charley asks Willy why he won't take his job offer, in which he would earn fifty dollars a week. Because of Willy's excessive pride and his inability to give up his identity as a salesman he refuses to take the job, insisting on being a hero by refusing all help. Now at the restaurant, Happy starts to flirt with an attractive girl, Miss Forsythe who claims to be a cover model. Happy idolizes Willy in part because he has always paid more attention to Biff and shares the characteristic of having little respect for women. Biff tells Happy that he waited in Mr. Oliver's waiting room for six hours and when he finally came out, he gave Biff one look then walked away. Apparently he did not remember Biff at all and Biff remembers that he was not even a salesman, he was just a shipping clerk but somehow Willy's constant exaggerations convinced him and everyone else in the family that Biff was more important than he really was. Humiliated, Biff snuck into Mr. Oliver's office and stole his fountain pen, fleeing the building. Biff tells Happy that he wants to confess this to Willy, wanting to break his cycle of self destruction by forcing Willy to see the truth for once. Happy tells him it would be better to lie, so Willy will have something to look forward to instead of more bad news. Biff begins to tell Willy what has happened when he arrives but before he can say anything, Willy tells him he has been fired. At this point Biff has kind of an epiphany in which he realizes that all the inflated dreams the Loman's have shared are extremely destructive and wishes to share this with his father. Willy tries to hide from the truth that Biff is telling him but instead focuses that Biff's failing of math was the source of his troubles because Willy refuses to take any responsibility for Biff's failure. While Willy is still in the bathroom, Biff puts the rubber hose on the table and exposes the ugly truth  that they know about his attempts to take his life and they can no longer afford to ignore it. Biff rushes out of the restaurant embarrassed and Happy follows him, abandoning their father in the restroom. In the restroom, Willy relives the memory of being surprised by Biff in Boston while he was with the women he had an affair with. Biff enters ashamed that he failed math and begs Willy to convince the teacher to let him pass, again showing that Biff doesn't believe in hard work and instead wants his father to save him. Wanting to rush him out of the room before he sees the woman, Willy agrees to help Biff pass math but this leads to Biff mocking the teacher which leads to the woman revealing herself. This part in the plot is one of the most important parts in the book, it reveals that in the face of lies reality will ultimately reveal itself. Biff realizes that the man he admired is just a lie and a phony and the falseness of the values Willy instilled in him. After the memory,
Willy leaves the restroom begging Stanley, a waiter at the restaurant, for a place to buy pea seeds which I believe is because he knows the end of his life is coming and he wants to leave something behind. Biff and Happy return home later that night and their mom reveals that she sees the truth behind her sons even though Willy can't. She sees the boys for what they really are, accusing Happy spending time with all of his "rotten lousy whores" and asks Biff if he cares whether Willy is alive or dead. She also yells at them for abandoning Willy at the restaurant and demands that they both pack immediately and leave the house. Happy continues to live in a constant lie, telling his mother he had no part in abandoning Willy while Biff in contrast has began to confront the negative aspects of his personality and finally realizing his whole life has been a lie. Linda tells Biff that Willy is in the garden now, obsessively planting seeds. In the garden, Willy is talking with Ben and he mentions the fact that he has a twenty thousand dollar life insurance policy his family gets when he is dead. He also adds that at the funeral, his family and Biff will see how many important he is from the number of the people there. This shows that he continues to think that being well liked is the most important thing and his continual belief in the American capitalist system even though it has failed him. Ben counters that it would be cowardly and knows the truth behind it. Biff enters and tells Willy that he is leaving, even though Willy believes he is meeting again with Mr. Oliver tomorrow and Biff tells him that he is not in fact meeting with him. Biff believes the fact that he is leaving and not going to stay in touch is an act of love but Willy believes it is abandonment and responds that Biff is throwing his life away in spite. Biff brings out the rubber hose in front of Willy and tells him that committing suicide won't make him a hero and accuses everyone in his whole family of making delusions. He charges Happy with making his job title seem more important than it really is and tells his father that the three months he was out of touch was for being in jail in Kansas City for stealing a suit. He reveals that his father's unrealistic goals for him have made it impossible for him to be a functioning part of society  and he ruined his life by feeding him continual lies. Biff continues to explain how he really wants to just work outdoors and that is his true love, and these revelations throughout the play have caused him to value more important things. Sobbing, Biff goes upstairs and finally realizes that Biff has loved him this whole time and Happy and Linda assure that to him. Happy goes upstairs and Linda follows him; now alone Willy tells the ghost of Ben that Biff will be highly successful one day, once he has twenty thousand dollars. Willy says goodbye to the house and as Linda is telling him to come to bed, the Loman family hears the car growl to life and drive away as Linda, Happy, and Biff rush downstairs. This last part symbolizes that Willy thought that abandoning his family in order to make them wealthy was more important than being a loving father or husband, and his unrealistic sense of the American Dream.
