Depends on the prison. US prisons have the goal to get you back into prison after release.

I would say that private prisons in the US (or elsewhere) are incentivized to reduce human rights over time (by expanding prison stays). This can be anything from subverting early release/parole or expediting additional charges/convictions, such as being involved in a fight inside prison.

Private prisons, civil asset forfeiture and property taxes are probably the three most common things the govt does that I disagree with outright on moral grounds.
