Only for people that are black or poor.

True, however there are bs for-profit elements to even the non-for-profit prisons. Predatory costs to calling / commissary / etc. that still benefit companies when the US imprisons more people.

Even "not for profit" prisons are lining millionaires pockets with infrastructure and maintenance contracts.

And many states let private companies charge accused people up to $40 a day for the ankle bracelets.

Listen I live in the USA, but if thats your best pushback to all those facts - should tell you what a dire state we are in. And prisons that aren't for profit still send out prisoners to for-profit industries to work, so it's kind of a moot point.

And how many of these other prisons offer up their prisoners as extremely cheap labor to businesses that ARE for profit?

That's still about 96,344 people. Which is nearly double the total prison population of Spain.
