What the evidence has suggested
Michel Foucault's argument in Discipline and Punish was not simply that prisons fail at rehabilitation. It was that they succeeded at something else entirely: producing institutionally dependent, socially stigmatised and economically unplaceable people, which are precisely the conditions that make return to prison almost inevitable. Applied to India, the insight is devastating. It explains not an aberration, but the design logic of the system we continue to defend. A person who enters a closed prison loses her family contact, her income, her vocational skills, and eventually her sense of independent agency. She exits with a criminal record and into a labour market that will not receive her. We have, over decades of institutional inertia, built a system that manufactures the very failures it claims to punish, and then treats their return as surprise.
