Political take, Prison Industrial Complex
Prisons are just glorified slave camps, one might agree and add "now" but, I fail to see any time in history where imprisonment isn't a tool for oppression by the status quo.
Ultimately, the goal should be to abolish prisons completely, but for people to be receptive of that, we need to do a lot to address psychophobia, ableism and generational poverty that plague our society and cause us to commit crimes.
Punishment does not solve problems, it does not undo the harm, all it does is make an example out of the wrongdoer, via state violence, as a fear-based deterrent to the rest of the population. I think rehabilitative and restorative justice is a far better use of our time, and does more to prevent crime from happening.
After all, people who are truly content with their lives wouldn't be motivated to cause harm to one another.
