How did California go about “the largest prison building program in the history of the world” (Rudman and Berthelsen 1991: i)? We have already seen that California’s political economy changed significantly in the 1970s, due both to changes in the location of industrial investment—capital movement—and to “natural” disasters. Those changes, and responses to them, provided the foundation upon which new rounds of capital movement and new natural disasters were played out. These shifts produced surpluses of finance capital, land, labor, and state capacity, not all of which were politically, economically, socially, or regionally absorbed. The new California prison system of the 1980s and 1990s was constructed deliberately—but not conspiratorially—of surpluses that were not put back to work in other ways. Make no mistake: prison building was and is not the inevitable outcome of these surpluses. It did, however, put certain state capacities into motion, make use of a lot of idle land, get capital invested via public debt, and take more than 160,000 low-wage workers off the streets.
