Gilmore's Golden Gulag gives carceral geography one of its most rigorous materialist anatomies. The iconic idea is the prison fix: the expansion of California's prison system as a geographical solution to overlapping surpluses of land, labour, finance capital and state capacity. The theoretical contribution lies in refusing moralistic explanations of imprisonment as mere crime response, replacing them with a political-economic account of crisis management, racialization, rural restructuring and state-building. Gilmore's method is spatial and evidentiary: she reads budgets, agricultural transformations, labour markets, electoral shifts, prison siting and grassroots opposition as parts of one carceral apparatus. The book's operational force comes from its capacity to show how punishment is built, financed, territorialised and contested. Its bridge to the wider field is abolitionist geography, where infrastructure, race, surplus and organised resistance become inseparable. Golden Gulag converts prison studies into a theory of state space under conditions of crisis.
