Honestly if I’m ever imprisoned for being homeless and it doesn’t look like there’s a way out, you can be damn sure I’m not going to willingly work. They must provide three meals and a place to sleep and that’s all I will do. At that point I have no home and the carrot of “getting out” isn’t there. You’re not getting my labor for free too.
And for those unaware, solitary confinement permanently fucks up your brain hard. We are social creatures and the lack of socialization will make you unable to reintegration into society, and make you more likely to lash out with violence.
It's either forced labor (slavery) or brain damage. Nobody should have to choose between that.
