No, he's pointing out that bonded slavery is not the same as wage slavery, as the element of free choice/freedom from harm doesn't exist in bonded slavedy.

I see the equivocation of suffering between bonded and 'wage' slavery to be incredibly disingenuous. Working at McDonald's doesn't make you a slave in the same sense as a person who has their limbs cut off for trying to escape, and to insist that 'wage slavery' is comparable is disturbingly detached from reality.
