The post you are reporting:
If prison was the kind of place you really don't want to go back to, that might deter a few offenders, but it isn't.
I'm sure there are many people who are institutionalised, who don't have much of a proper education, find it difficult to get a job and so treat it as "home"; they are accommodated, fed, looked after, any treatment they need, they're given, don't have to worry where their next meal is coming from, have no concerns about heating bills etc etc. so prison is a good option for many of them.
I must be honest I am not the sort of person who would treat these criminals with kid gloves, but would make prisons less corrupt but harder, make them work for their "accommodation" and all that involves, but also provide real-world vocational courses in prison so they can turn their hand - where appropriate, to something useful and honest.
There is a very small percentage of people who go straight after prison, so it really does need a lot of serious thought, not softly softly woolly-headed stuff.
