No, it isn't.<quoted text>
We also know that the 13th Amendment to the Constitution that barefoot keeps referring to has ensured that slavery is still legal in the USA.
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.
Congress shall have power to enforce this article by appropriate legislation.
Involuntary servitude can be a sentence to hard labor imposed for a crime, or a sentence to work for community service, or a sentence to work as restitution for theft.
Slavery is not legal in the U.S.
Sorry to disappoint you.
