"What is the function of prisons? Above all, to keep people docile in other prisons, Prisons are necessary not to pres eve order so much as to protect and enforce the inequalities produced by the market. The coercion and control they represent isn't an aberration in an otherwise free society, but the essential precondition for capitalism. Prisons are simply a more extreme manifestation of the same logic inherent in property rights and national borders."
