Functional Incarceration and rehabilitation

As many know the United States uses incarceration as a form of rehabilitation for the men and women that commit crimes. Although the U.S. has the highest number of incarceration's per year then any other country, so whats this say for the people in the U.S.

With respect to those that are incarcerated most of them are being reshaped to what society expects of them and that is the functional part of incarceration even though not all that get incarcerated become rehabilitated so that poses a non functional aspect of incarceration
