Are you really making the case that no white-collar criminals should go to prison? I guess I can see where you're coming from, but I personally think that we need more financial fraudsters behind bars. You know, the whole "rule of law" and "deterrence" business.
Personally I think the whole concept of prison is primitive and should be done away with. If someone is violent then they have something wrong in their head and should be treated. I know that currently asylums can be worse places than even prisons, but once we move away from this draconian "people must suffer so I can feel better about wrong in the world" strategy we can move much more focus on getting treatment and detection right.
This is not always possible.
You know that politically-correct killjoy who always speaks up about how distasteful and offensive prison rape jokes are? I'm that guy.
That seems like a compelling case for reforming the prisons into a place where you're punished for your infractions against society, but not abused or raped. Prison shouldn't completely destroy someone's life, either. We need to have meaningful ways for prisoners to re-enter society as productive citizens. Otherwise, things never get better.
Part of the problem is that it's really hard to win an election against someone who has positioned themselves as "harder on crime" than yourself. As a result, we have legislators pushing for tougher and tougher prison sentences, mandatory sentencing, etc. I don't know how other countries deal with this pressure, but I would be eager to see the United States do better.
Just a friendly suggestion.
