As a means of correcting the socially harmful tendencies of a person committed to the commissioner of corrections, the commissioner may require participation by the person in vocational, physical, educational and corrective training and activities and conduct and modes of life as seem best adapted to fit the person for return to full liberty without danger to the public welfare. The commissioner of corrections may receive money from the sale of articles manufactured by a person committed to Corrections Department’s custody and confined in a correctional facility under the control of the commissioner and expend the money so received for the purchase of materials to be made into other articles for sale.
