"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."

- 13th Amendment of the U.S. Constitution

We house 25% of the world's prisoners in part because it's how we are still legally producing slaves.
