In general, Death of a Salesman is an indictment of the American capitalist system which values machines more highly than men. However, the protagonist, Willy, is not being efficiently sacrificed to business efficiency but has failed as a common man who has a false way of life compared to Charley`s. Charley, who is successful, is the exact antithesis of businessman Willy himself. The central conflict is the father-son conflict, but it is the presentation of Willy`s internal life which is the most striking feature of this play. There are three categories of culture in this play. First, culture includes physical aspects such as properties, setting, stockings, refrigerator and car etc. Second, culture is connected to behavior and life pattern such as Willy`s ostentatious attitude. Third, culture is interrelated to the thoughts and values of Willy and his family members. These three categories are interconnected in forming the characters` way of life. In conclusion, Willy is a common man who has self-delusions and false values. He has no sense of the right values which will lead him to become a right person.
