There's no such thing as guaranteed profit in a free market system, yet free markets seem to provide ample incentive for players to participate. Obviously, there's no guarantee that a former inmate won't commit another crime even if the rehabilitative measures he experienced while doing time were exemplary. However, there's also no guarantee that in the university example a graduate will find a well-paid job. Still, there are universities that have successfully implemented this business model. There's a whole industry that's predicated on this kind of uncertainties: The insurance industry. While there's no guaranteed outcome risks and probabilities can be calculated and factored into the price of a service. The question perhaps is: What value do we as a society allocate to a former convict likely not committing crimes in the future anymore but contributing to society instead? Considering the alternative, i.e. a former convict not only being a liability to society but also being highly likely to commit crimes in the future, I'd that service should come with quite a high price tag.
