In regards to the OPS recent edits, I think there already is an option for inmates to submit themselves to experimentation if they wish, though I can't be certain. Even if that isn't the case, I don't see the point of introducing that system seeing as how we already provide opportunities for ordinary members of the public to offer themselves up for experimentation.
Alright, let us try a different avenue. Is it right that prisoners should be made to work long hours without receiving a minimum wage? America, for instance, specifically refuses to accept imports made by slave labour (no, sweat shops don't count and no, it isn't anything like slave labour), yet the country is heavily reliant on prison labour. Prisoners work many hours for only a tiny wage. As prisoners, they have no choice in the matter. The US prisoners manufacture a huge number of products for the public - is that not slave labour? Is that ethical? At what point does a punishment shift from justice to exploitation?
