lol. Free doctor, eh?
Someone's been feeding you a line of propaganda.
You get incarcerated, if you're *lucky*, you'll see a doctor after a few months, and even then, probably only if someone beats you within an inch of your life.
The free medical care? Mostly myth, and absolute bottom feeder quality if you do get any. Too little, too late if it's serious.
The free food? Trust me, you don't want to eat it. Any of it.
The free room / roof? Sure. Complete with free beatings, rape, and deaf/blind guards. And an hour a day in the yard. Pick your power group.
The free education? Awful. You can't use it anyway, you're a felon. Start figuring out who and how to rob, because that's the only decent-paying job you can get hired for now.
Jails and prison in the US are hellholes, the inevitable fruit of the popular retribution-centric mindset combined with scare-the-populace political maneuvering. You approve, okay, that's your call but don't try to sell those places as poverty relief. There's no relief to be found. Of any kind.
