"Golden ___: Prisons, Surplus, Crisis, and Opposition in Globalizing California" (book by Ruth Wilson Gilmore) (5)
I believe the answer is:
gulag
(Other definitions for gulag that I've seen before include "Soviet forced labour camp(s)" , "Russian labour camp system" , "Russian prison camp for political prisoners" , "USSR system of labour camps" , "Russian prison and labour camp organisation" .)
