Both local law enforcement and the for-profit companies behind our jails profit enormously from the US having the highest percentage of population incarcerated of any first world country. The majority of individuals currently doing time are in for drug-related crimes.
We have the highest incarceration rate, full stop.

For-profit prisons, however, are the most direct beneficiaries of the (completely fucking insane) "war on drugs". For-profit prisons are one of the best examples of how an otherwise fairly functional democratic society can end up with a system of profoundly deranged incentives that visits grievous harm upon a staggering number of people.
These institutions conduct a program of systematic, industrialized dehumanization of millions of people -- including millions of people who have never harmed another person. In my view, this makes them evil, profoundly evil.
Although this sounds extreme to some people (especially those who have never paused to think it through), I put America's industrial prisons in the same league with the Nazi extermination camps. America doesn't actually starve people to death or gas them in ovens, but that's a matter of degrees. America does separate children from parents and force nonviolent human beings to live out their lives as caged animals. Millions and millions and millions of them.
There is not much about America so disgusting and disgraceful.
>Its purpose it to line the pockets of the politicians who support it. I would say that it's more for the large pharmaceutical companies. Politicians are cheap these days, and the profits from the "war on drugs" are orders of magnitude larger than the money given to politicians to support it. The ATT/T-Mo merger "only" had $9 million in lobbying support -- an order of magnitude less than they stand/stood to lose if the deal fell through REF: http://www.electronista.com/articles/11/12/09/attmay.have.tr... .
