According to goffman, whom are we sending to prison and simultaneously, what else are we ‘saddling' these people with?

According to Goffman, We are sending poor kids in prison and putting them restrictions on them and paying court fees.
He belibed that people who are placed in prisons are the people who are seen by threat by society for failing to conform to a certain value/ideals that the majority of people in that society held.

You don’t list any options but the one that frets overspending and the consequences of that.
