The title of this thread is highly misleading, it has nothing to do with slavery and everything to do with the rights of individuals to protect their work.
Which means it's not slavery, but it is theft. It would only be slavery if someone was forcing you to make content for no pay, rather then simply stealing the content you already made.

Slavery in the US takes place almost entirely in prisons.
Not just prisons (though I agree with you). Human trafficking is a multi-billion dollar a year black market industry and has major hubs in numerous cities across North America.
