This book argues the market economies upheld by global cities rely on waste production to the same extent they rely on capital production. Useful commodities, including food, must become waste to make room for new commodities worth more in the eyes of the market. This keeps the economy pumping. However, the system adds to the growing problem of waste production and ostracizes, even criminalizes, individuals who do not operate within this market system. Here lies the author's main argument.
The argument mainly draws from a soft anarchist group called Food Not Bombs, which takes leftovers from businesses and even dumpster dives for ingredients they can transform into free meals for city residents. Cities essentially criminalize this counterpublic for operating outside market forces, especially through city ordinances prohibiting group-level food sharing in public spaces. Individuals who do not or cannot operate within the market are criminalized further through laws prohibiting squatting, going to the bathroom outside, rough sleeping, etc. Such market logic leads to absurdities such as cities that have enough food to feed hungry residents, but do not distribute that food effectively, or cities that have enough housing for their entire homeless population but prefer to keep those spaces empty for the sake of the market.
Global cities contain various such absurdities and inconsistencies, but rather than call for a complete overhaul of the capitalist system the author argues counterpublics such as Food Not Bombs can exist alongside the market public upheld by powerful states and individuals, albeit uncomfortably. Though their contribution seems small, Food Not Bombs redeems edible food set for destruction to feed individuals who otherwise might have gone hungry--a success for those commodities and individuals society deemed unsuitable, and a reminder that conventions and systems need to be challenged to allow people their full humanity.
"The revolution will be catered!" was one of my favorite lines from this ethnography.
