Hm, some notes:

- I would say that extracting capital from labor does not constitute "slavery" in the sense of either de facto or de jure "ownership" of humans, but a wider interpretation of the word may apply.

- Exploitation doesn't have to be fraud. People can be willingly exploited. If we imagine for the sake of argument that human suffering can be quantified, and we imagine a person who starts from a place of, say, a 10 on an arbitrary scale where that's pretty bad (and 0 is no suffering), they may "choose" to take a job that reduces their suffering to an 8. Despite the reduction in suffering, someone else benefits from this arrangement more than the suffering human, and the benefited person could have chosen to reduce the suffering further but for the increase of their profit. This is still exploitation, even if the sufferer was made aware of all the circumstances up front.

- I said that the people's psyches were damaged; nothing about "psychic damage". One example of damage to the psyche is being asked to classify images of CSAM for eight hours a day. Regardless of the pay, this causes damage to people with even the barest shred of empathy.
