The American justice system seems to be based upon profit, and keeping people reoffending in order to continue keeping the justice system in place. There is no incentive to reform as the system currently stands. It is a major failure of society that recidivism is an expected consequence of being "in the system."
I used to think that it was biased towards profit, but after the last 5 or so years, I think that's just a side effect. American society believes strict and long punishment for wrongdoing is the solution to crime. We had a wave of progressive AD's elected into office and they barely lasted 3 years, they're all getting booted.
The profit part of it really came down to "well, just punishing them is leaving money on the table!"
Now, it might be the case that the people profiting from the string and long punishments are so cynical and greedy that they started campaigning for longer, harsher sentences specifically for their own enrichment, but the people are buying it as purification and penance through pain. The prison industrial complex only works as a business because the people already want what's being sold to them.
