'...Some of those moneymen might have been legit. There might be some dough around at the end of this.'
'You don't understand. The money men didn't have any money either. It's clear what they were.'
I looked at him until he said,
'They were all actors.' (pg. 332)
In the cathartic ending of Martin Amis' Money, protagonist John Self begins to realize how many people in his life were simply acting as various roles. Both films, Good and Bad Money, don't actually exist. Fielding Goodney has manipulated Self into signing various contracts that are really various loans and debts; and he's also been the mystery caller, Frank (and thus, it is implied that Goodney is also the red-headed transvestite who has been following Self). Returning, dejected and broke to London, Self also discovers that Barry isn't his father at all; his father is Fat Vince.
All of these things are amplified by the general impression throughout the novel that John Self wants to escape from the world of the book. At various points in the novel he addresses the reader mournfully, making statements that make our world/mentalities as far less base, less pornographic. There is something outside of his world that we as readers know, but that he cannot. It's also interesting to note that since this is a suicide note, Self dies when the story ends (at least to us he does). Self says at one point that his journey has "no destination, only an end.". He's experiencing conflict between a desire to explain his past and his present, and his desire to leave this world. How impressive then, when Amis shows the reader that his past and present worlds are merely scenes being fabricated by various part-time actors; while Self has believed himself to be in control of the money and people around him, its clear that he is the one who has been the most manipulated.
