even if one is concerned with remarkable similarity of prison labor to slavery, implications of 13th amendment clause, etc., most of the prison labor is for wholly-government-owned enterprises, frequently manufacturing things for other government departments. As another example, Louisiana is phasing out private prisons. That should be great! Meanwhile Angola (state-run) continues to have prisoners picking cotton. I know people know about this because they always bring up prisoners picking cotton in these conversations, but then the talking point remains "private prisons" somehow. So I still don't get why this idea is so sticky.
