the thirteenth amendment allows for slavery; police are slave catchers, prisons are slave plantations and factories. if you dont have your money taken in court, they take your freedom; the court system is notoriously lenient towards people (which ludicrously includes corporations) who can afford better representatives/more expensive strategies.
if you want labor reform, you need to start with the systematically unjust criminal "justice system."
The most common and stable society since the dawn of agriculture has been the feudal/slave society.
Countries like China and Bangladesh are basically this type of society.
And even the USA had sharecroppers until very recently.
We have to be very diligent, every waking hour, if we want to preserve our modern western way of life.
And we are horribly failing, by getting sucked into divide&conquer tactics that polarize the working class and thereby neutralize our political power.
The US still used slavery as a source of labor up until about the mid 20th century. Southern states would do "prisoner leasing", where prisoners were basically given to farmers and plantation owners to do labor for free. It started right after the end of the Civil War. Many black boys and men were arrested on trumped up charges and "leased" back to the same plantation owners they were freed from.
