When talking to Danny about the book this was also one of his main take always. I asked about whether I should avoid imposing my own reading and he said that it would actually help because the theme can actually be so dense and hard to grasp at points that visually tying it down with an interpretation would actually help.
So, considering the new themes of consumerism and group delusion I instantly made the connection to hallucinogenic drugs.
I quickly sketched out a few more ideas around this theme and came up with quite a few parallels between consumerism and drugs. the most effective three were:
Cocaine as Gold Dust
Gold coin as LSD
liquid gold as heroine.
I think the two most effective communicators are the cocaine and the LSD just because they have the tone of unpleasantness without possibly being too dark. Adding these to the two strongest from my last idea generation session I have 4 total to pursue further.
