9% of prisons are private, which is 9% too many, but it's the citizens who have to endure open drug scenes who are behind the push to end them.

This problem is described, wrongly, as homelessness, by both advocates for ending open drug scenes, and by activists who view themselves as working on behalf of the unhoused.
That's not the effect of their activism. The effect of their advocacy is to increase misery. Open drug scenes make the city unsafe. Open drug scenes draw the temporarily homeless into a shadow market of addictions and prostitution.
Open drug scenes are bad for everyone who has to be near them, but they are particularly destructive to the mentally ill addicts who constitute them.
I'm sure private prisons would love to turn all of us into literal slaves, but if we reduced the number of them down to the correct 0%, urban residents would still be demanding the end of open drug scenes.
They are right to do so. Supporting open drug scenes is supporting misery, harm, assault, theft, overdose, rape.
Don't support open drug scenes. Make sure your donations to help the unhoused don't support open drug scenes (this is difficult).
Also, let's end private prisons. It was never a good idea and it won't get better with time.
