In addition to solving overcrowding and cost problems, some advocates of privatization suggest that private corrections can enhance offender rehabilitation. Privatization efforts in the 19th century and the level of interest in rehabilitation reveal at least four types of rehabilitation-related difficulties to consider before large-scale correctional privatization efforts are implemented. These difficulties include the lack of interest in rehabilitation, the existence of substantial interest in correctional cost management, consequences of free market instability on program integrity, and the potential for inmate abuse produced by a profit-driven system. Whatever the likelihood of successfully implementing effective private rehabilitation programs, the value of private sector involvement in corrections will not likely be judged on this dimension alone. 53 references.
