In The Great Gatsby, how is the relationship of Tom and Daisy destructive?

The relationship that Tom and Daisy share is destructive
on a couple of levels.  On one hand, it is destructive to one another because there is
little in way of real understanding or real sharing present.  This poor foundation
results in a marriage that exists really in name only.  Both of them view the other as
an object.  She views Tom as a glorified bank account and he views her as a trophy. 
With this, both of them not only objectify one another, but everyone else.  They are
incapable of fostering any real connection with anyone and see individuals as means to
ends as opposed to ends in of themselves.  In their relationships with others,
destruction is evident.  Gatsby is destroyed by his relationship with Daisy and Tom
effectively ruins the Wilson.  In large part, Fitzgerald makes the argument that
individuals whose relationship foundation is corroded bring this level of impurity to
other relationships they foster.
