“Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction,” reads the Thirteenth Amendment, commonly known as the amendment “that ended slavery.” However, there’s still a group permitted to be forced into involuntary servitude: prisoners. In most US states, incarcerated individuals being forced or coerced into performing labor against their will in dangerous conditions, and for little or no pay, is still legal.
