Yes, I think raising the age of consent would definitely be helpful. It would be helpful because there could be no confusion when an agent or scout or whoever is in a position of power over a young girl and things get ugly. I definitely think there is no 14-year-old who really wants to find herself in that situation. I have yet to meet one.
So, yes, raising the age of consent would be a start. It would eliminate even questioning whether that 14-year-old on that set that day was really willing and wanting to be there.
