What are the similarities and differences between Biff and Happy Loman in "Death of a Salesman"?

Similarities: 1. Both cling to their father's idea of having "personal

attractiveness" as the criteria for success.

2. Both appear to discount their father's (Willy) views and

dreams about life early in the play.

Differences: 1. Biff is lazy and seems to have no ambition in life;

Happy is working and hoping to get ahead in his job.

2. Biff is the oldest son, Happy is the youngest.

3. Biff is the son that Willy sacrifices himself for, not for

Happy.

4. In the end, Biff is the one who sees the reality that is

the situation and his father and Happy still believes

that Willy at least had a dream and "did not die in vain."
