This paper focuses on the impact of the corrupted American Dream on Willy Loman’s family, with a particular emphasis on Willy Loman’s disillusionment about the meaning of the American Dream and its attainment. By analysing the American Dream in Death of a Salesman, the aim of this paper is to show how Willy’s misconception of achieving the American Dream led to a miserable and unsatisfying life for not only Willy, but the whole Loman family. The cause of Willy Loman’s demise was brought about by his obsession with the American Dream and his delusion that being well-liked, popular and physically attractive would lead to success and material wealth. Willy’s delusions of the American Dream caused not only his failure, but also the failure of his sons. The different ways to achieve the American Dream in the play will be crucial for understanding how Willy’s dream was a misconception. On the one hand, the characters of Willy, Happy and Biff will be introduced as the characters whose misconceptions of the Dream caused negative consequences and even the death of the dreamer. In contrast, Charley and Bernard will be the main examples of characters who show that the American Dream is possible if one recognizes its true values and what it takes to achieve it. Finally, in Death of a Salesman, Arthur Miller calls attention to reasons for the downfall of the American Dream and hints at ways to reestablish the true values and the future of the American Dream.
