They’re are a few problems saying that prison labor is a continuation of slavery in the US.
The largest demographic in prison is white men.
Prisons don’t make money. Corpos that run the prisons, or the phones, or use prisoners as cheap labor do profit, but that money mostly comes from the State, the prisoners themselves, and the prisoner’s families.
Prisoners have legal rights.
Nobody is born incarcerated.
I’m not trying to defend that clause in the 13^th^. But equivocating all forms of slavery and forced labor is a common white supremacist tactic to minimize the particular evils of racialized chattel slavery in the US.
All races, all people, all nations, have had slavery and been slaves at some point themselves
