Criminals have been a problem for as long as humanity has existed. In the year 2569, all people convicted of crimes are sent to the planet Zeautian, where they are put to hard labor mining precious metals and ore for 16 hours a day, or farming on large fields to support other planets populations. The planet houses 9 Billion prisoners, but it only has 500 million guards. The main point of the prison is to collect the resources of the planet, and secondly to rehabilitate the prisoners. So, what would be the most effective way to run the prison with both the aforementioned goals in mind?
The prison is supposed to be run like a Terran penitentiary, prisoners have 16 hour shifts, with three lunch breaks, one shower pre day, and 8 hours of sleep. All the prisoners are occasionally watched by camera-bots.
The prisoners are only able to access farming vehicles and tools, and mining equipment, and semi-decent sanitation, everything else is below medieval tech.
The guards, on the other hand, are well equipped with powerful equipment. The mostly refrain from contact with the prisoners, with most guards stationed on isolated islands in the middle of oceans that the prisoners can’t access, or near the arctic and Antarctic circles of the planet. They are equipped with advanced helicopters, powered armor suits, plasma rifles, and etc. To add another line of defense, the guards also placed the some of the most monsterous creatures in the galaxy around their stations, to eat up any prisoners straying to close.
