is the need for prison simply the side effect of a population density that is too high? But that is a different topic. The issue is the cost of incarceration and how a once noble idea (eliminating bad behavior instead of eliminating the owner) has been 'corporatized'. It seems a fundamental rhythm of human activity is to express the goodness in us with a new idea. The evil in us then tries to maximize profit and efficiency resulting in a loss function that destroys initially unrecognized but important parameters of humanity.
