So slavery has taken MANY forms throughout history - the form most people are familiar with is american chattel slavery “a form of slavery where individuals are treated as personal property and can be bought, sold, or owned indefinitely”. There are lots of other forms of slavery many that don’t including purchasing humans, and the US prison labour system is slavery beyond the shadow of a doubt.

Why beyond the shadow of a doubt? Because the 13th amendment abolished slavery and involuntary servitude, except as punishment for a crime.

Also, since the US prison system allows prison labour to be sold to private corporations, you can actually buy a prisoner’s forced labour.
