What is the relationship between Ben and willy in the play, Death of a Salesman?

Ben would like Willy to take after him, move to Alaska,
take a chance, work outdoors, and become a true
success. 

Willy esteems and admires Ben and is tempted to
do exactly what Ben suggests. However, Willy is persuaded by a more corporate version of
the American Dream and he remains at home, with his family, attempting to work his way
to partnership with his employers. 

Ben represents both
boldness and the achievement of wealth to Willy. These characteristics can be seen as an
articulation of self and self-determination which eludes Willy, who is not in a position
of self-determinacy or potential success. The fact that he commits suicide as  a money
making venture is a clear indication of Willy's lack of economic
potency. 

Willy's relationship to Ben, then, can be seen
also as a representation of Willy's relationship to success (and
failure).
