There’s also the age issue: all three industries I mentioned employ children and adolescents to a large extent than, say, the truck-driving industry or construction industry. Add the oversupply factor to the employment of children, and you have an even higher likelihood of abuse, because people who want to have sex with kids are abusers by definition, whereas most adults in adult relationships are not.
While I don’t necessarily disagree with you, I’m not in the excuses game.
If it happens, it’s wrong.
