Where else are profitable prison industries to find workers? Edit: This is a slightly complex relationship but it holds. Once you start down a path of mass incarceration, there's pressure to find a profitable use for prisoners. Once you have a profit-making use, there's a demand for more prisoners. So while it is chicken and egg, it's pretty clear that the demand is a factor today. It is also worth noting that the the 13th Amendment specifically allows slavery as punishment for a crime.
