In "Americanized" by Bruce Dawe what extended metaphor (conceit) does Dawe use?

To express
the relationship between American consumer dominance and Australian emergence into such a realm,
Dawe uses theof a mother and child.  The mother is emotionally distant from the child.  She is
able to spout of self indulgent notions of identity that have been carved out of Madison Avenue
brand of consumerism such as "I think young, I think big, therefore I am." She is
unable to emotionally connect with her child except for when the child engages with her toys.
 All of these are American name brand items like soft drinks, hot dogs, and chewing
gum.

The Australian identity in this relationship is the child.  The child is
shown to be emotionally adrift in the poem, "a vague passing spasm of loss."  The
emotional estrangement compels it to see any attention, even a consumerist manufactured one, is
better than no attention.  For the child, being able to embrace what the mother does is almost a
tradition being passed down.  There is something jarring about how this is a passing of the
consumerist torch from one generation to another, with nothing emotional remaining.  It is in
this light where the metaphor of mother and child serves to heighten Dawe's critique of
American consumerism on Australia.
