The % cut of $revenue is outside the main scope of my comment, which concerned child labor, a somewhat independent issue. It doesn't matter too much to me the % monthly revenue a 12 year old kid gets, I'm more concerned with the promise of unlikely riches encouraging kids to work long hours outside the oversight of traditional child labor laws. If that 12 year old is putting in a 30 hour work weeks then I think it's problematic regardless of the revenue with some minimal enforceable guardrails. I don't think parental signoff is sufficient either: the entertainment industry has plenty of examples of how that can go wrong, and also how some of those minimum guardrails might work.
