Public schools accustom children to the discipline of the capitalist workplace; children are separated from their families to perform a series of tasks alongside others, under the direction of an authority figure, according to a schedule ruled by a clock. The school reform movement of the 1830s and 40s also aimed to shape the students’ moral character. The effect of this was supposed to be that students would willingly submit to authority, that they would be able to work hard, exercise self-control, and delay gratification.
In fact, the concepts of good citizenship that came out of school reform movement were perfectly aligned with the concepts of criminology that were being invented to categorize people on the street. The police were to focus not just on crime but on criminal types—a method of profiling backed up by supposedly scientific credentials. The “juvenile delinquent,” for example, is a concept that is common to schooling and policing—and has helped to link the two activities in practice.
