Gordon is the UMBRELLA

In Gordon's lengthy monologue he describes himself as an umbrella to connect people who need organs with people who need money.  Since the entire play utilizes an umbrella motif, I did some research on the historic symbolism that umbrella's hold.

The importance of the umbrella can be traced back to Buddhist beliefs:

The umbrella is carried above an important dignitary or the image of a deity, to indicate that the person or symbol below the umbrella is in fact the center of the universe, and also its spiritual support.

Umbrella's were also viewed as protective items -- protection from the outside elements.  Gordon does seem to offer protection -- perhaps protection from going bankrupt, and protection from dying.  To those people who Gordon is helping out, Gordon is a savior, similar to that of a deity.   Gordon not only provides protection for himself by finding a successful endeavor, but offers protection for all those desperate enough to seek help on the black market from his business.
