Slavery never left it just got rebranded.
The Thirteenth Amendment needs to be amended.
Per Wikipedia: The Thirteenth Amendment (Amendment XIII) to the United States Constitution abolished slavery and involuntary servitude, except as punishment for a crime. The amendment was passed by the Senate on April 8, 1864, by the House of Representatives on January 31, 1865, and ratified by the required 27 of the then 36 states on December 6, 1865, and proclaimed on December 18, 1865. It was the first of the three Reconstruction Amendments adopted following the American Civil War.
The US constitution expressly and explicitly allows slavery if it’s punishment for a crime. Read the 13th amendment if you don’t believe me.
