An underlying problem is that we've become addicted to prisons and punishment as a solution to all of our issues. The author didn't mention length of sentences, but the fact remains that we, in the US, impose sentences that are far longer than those in other western democracies. Over the past century, we've gradually increased the length of sentences imposed for all crimes, now sentencing people on the average to almost four times the length of imprisonment as we did a hundred years ago. That fact by itself guarantees a prison population at any given time which will be far larger simply because prisoners are staying behind bars four times as long when new ones enter the system.
On top of that, our current obsession with background checks for everything is actually causing more recidivism. When a person can't even get a job at McDonalds without passing a criminal background check, it means that the guy who got out of jail or prison is unlikely to find work. Do we really think that someone who can't find work and, by virtue of a felony conviction, isn't eligible for any sort of public assistance is just going to crawl off into a corner somewhere and quietly starve to death? When we eliminate all legal means of survival, we guarantee that people will use illegal methods to get by. I sometimes think that we really don't want anyone to succeed in rehabilitating himself when he finishes a prison sentence. Instead, we've set up mutually exclusive goals for everyone, insisting that prisoners have a release plan before getting out that includes housing and employment, and then do everything we can to make sure that they can't rent housing or find a job. We need to make up our collective mind about it. Do we want people rehabilitated and able to become productive members of society, or are we determined to create a permanent underclass of people who are marginalized and live illegally on the outskirts of society? If we want to stop spending more money each year on prisons than we do on education, then we need to abandon the present system which generates recidivism and guarantees a high percentage of people doing a life sentence in installments.
