How do the results of solitary confinement differ from the overarching goals of the american prison system?

The US prison system aims to promote social re-socialization of criminals who are unable to live in society. The results of solitary confinement differ from this goal in that they do not promote this social resocialization, but instead promote social isolation.

Explanation:

The US is virtually the only one in the world to incarcerate thousands of prisoners in solitary confinement over the long term or indefinitely. People in solitary confinement spend about 22 to 24 hours a day in total social and physical isolation with others. The problem with this is that this isolation goes against the main purpose of the US penitentiary system that wants to promote social resocialization so that these people can get back together in society.
