How can you relate Myrtle Wilson's and Jay Gatsby's deaths?

In The Great Gatsby, Myrtle and
Gatsby are both Alazons, impostors who move from rags to riches and
who live above their socio-economic classes.

Myrtle jumps
classes through infidelity.  Myrtles lives in the Valley of Ashes with George where she
is low class.  But, with Tom in their apartment in New York, she lives like the
upper-class Daisy.  She buys expensive dog collars and throws posh
parties.

Gatsby jumps classes through criminal activity:
bootlegging and gambling.  He comes from a modest background, but after he meets Dan
Cody, he reinvents himself and changes his name.  He partners with other gangsters to
make money during Prohibition.

Also, both are killed by
mistake.  Myrtle is run over by Daisy, but Myrtle thinks it is Tom's car come to rescue
her.  Gatsby is shot in his pool because George think he is Myrtle's lover and the one
who ran her over.

In the end, the American dream has no
room for opportunists and impostors.  Those who go from rags to riches end up in the
grave.
