In The Great Gatsby, how are the differences between new money and old money shown?

The perception of Gatsby is one way in which the
difference between old and new money is shown.  The folks of old money, such as Tom and
Daisy and Jordan, are going to consistently use Gatsby as the host of elegant and
elaborate parties in order to give him some level of acceptance.  However, the
acceptance given is one that is predicated upon him being conscious of his place.  The
forces of old money will never be able to fully embrace him because of his status as new
money.  For his part, Gatsby understands this and covets only this acceptance.  It is in
this light that he pursues Daisy and envisions himself in the manner he does.  Gatsby's
dreams revolve around the idea of being considered, at some point, part of the accepted
old money clique.  This motivation or desire is something that is fruitless, yet is
something that does not deter Gatsby.
