Slavery. The US still has constitutionally approved slavery.

The "prison-industrial complex" provides cheaper labour than the Chinese, which is why Americans imprison more of their own people than any country on earth:

In the shining promise of freedom that was the Thirteenth Amendment, a sharp exception was carved out. Section 1 of the Amendment provides: “Neither slavery nor involuntary servitude, except as punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.” Simply put: Incarcerated persons have no constitutional rights in this arena; they can be forced to work as punishment for their crimes.
