While I don’t necessarily disagree with you, I’m not in the excuses game.
If it happens, it’s wrong.
I agree that it’s wrong, every time, all the time. Using other people as objects is always wrong.
I’m just pointing out factors that allow it to happen in some industries more than others. Most of these situations are not acts of brute force. The victims are complying, rather than fighting, and being silent for decades, rather than naming names when something could be done, legally.
For adults, they know they have something to gain. With children, their basic weakness and conditioning to comply with adults is in play, but the “supply” factor is why their parents allow them to be in that position.
