It's a nitpick, but that's not in the bill of rights, if you're referring to the 13th amendment. ("Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted")
Of course, the fifth amendment can be construed to take away any right as long as there's due process (which is why the state can take away 2nd amendment rights from felons)
"...nor be deprived of life, liberty, or property, without due process of law..."
Good luck with that. Legal slavery is literally codified into our bill of rights.
