Minimum mandatory sentences reduce the chance of rehabilitation.  Minimum sentences force minor criminals to spend more time in prison, thereby increasing their exposure to more hardened criminals. This exposure reduces their chance of rehabilitation- other inmates act as a “bad influence.” [1] Furthermore, studies of labor market participation demonstrate that the more time a person spends outside the labor force, the more their human capital (i.e. marketable skills) deteriorate; their chance of finding well-paid work decreases with more time outside the labor force. [2] Longer prison sentences keep people from working, thereby keeping them in a cycle of unemployment that leads them back into crime.
