Slave labor is still present in America and in fact is enshrined in the US Constitution.

◾️US prison labor forces prisoners to labour and they can even get punished with solitary confinement if they are unfit to work.

◾️They work mostly for free or for under 1 dollar an hour.

◾️States keep prisons full and refuse to early release prisoners to alleviate overcrowded facilities because that would decrease the state acces to prisoner labor.

◾️Prisoners aren't allowed to unionize or seek legal assistance regarding working conditions.

◾️Massive well known companies hugely profit from prison labor.
