I dohbt that just because sexual abuse is shown a lot in places of power means its a bigger issue there.
Its probably a bigger issue in places of poverty and over crowding and less likely to be on mainstream world wide news when it does happen.
However the kind of abuse i think youre talking about happens quite often in show bussiness because people are more openly hired based on how well liked and good looking they are.
I think the problem with trying to police something like this is tough, and tbh it happens on every level of life.
Ive worked in plenty of warehouses were women got promoted after sleeping with a manager, and witnessed plenty of nepotism.
