You're right and I'm wrong. (Except I don't believe for profit prisons should exist . I see it as a monstrosity that is full of conflicts of interests)
As someone who believes in Unions and collective bargaining for better working conditions and such, I see this much like I do the Police Unions. They have gone way past a point where I can support their goals.
I give you a great deal of respect for saying that and apologize for my snark. I occasionally joke that the only unions conservatives like are the same ones progressive don't like.
To be clear, I don't much care about private prisons, I just don't think they matter all that much. Get rid of all of them all today, and all you've done is increase the population in the public systems. You still have all the issues associated with private prisons.
The thing I don't understand about the anti-private crowd, its not as though self-interest and greed go away just because the obvious profits are removed.
Edit to add. What I really like to see is some State work out a bonus program for private prisons that rewards reduced recidivism. Something like, they get an extra 10 grand for every 10 years a former inmate doesn't re-offend. We might actually see some sort of innovation that might actually improve society. Hell, even if all they do is give ex-cons low end jobs that might be an improvement.
Anyrate, prior to getting rid of private prisons we need to:
End the war on drugs, at least decriminalize.
Let ex-cons vote.
Stop preventing them from getting decent jobs after they get out.
Increase education in prisons including general ed and vocational training. Let unions set up shop in prisons to teach plumbing and what not.
Take a look around the world at the systems that have reduced recidivism and do some of that.
Convince Americans not be so vindictive.
If you look at incarceration rates, crime rates, and growth of private prisons over time. Private prisons trail. Crime rose from the 60s and peaked in the 90s. Incarceration rates increased late 70s and early 80s. The private prison industry started just a bit after that.
