Check out the work of James Gilligan. I watched a few minutes of his videos on line, and was struck by the point that several studies have shown that education is the most effective antidote to re-offending yet discovered. There wasn't a modest difference - somethinh like 2% after 30 years (by those educated to Bachelor's level or above) compared to 60% after 3 years.
And education can be delivered cheaply, using on line videos, or DVDs, or even conveivably interactive teaching over the internet. In an RBE, of course, education wouldn't be withheld from people so that educators can make money out if it. All educational material would be open source.
