An undue amount of pressure is placed on child performers, and they should be banned. They are just children, but they are being forced to work just as hard as adults. They need a childhood so that they can develop like other kids and go on to have a successful life.
I believe it should be up to parents to decide if their child is under too much stress and pressure as a performer. I am strongly against any laws restricting freedom to citizens of any age in the name of protecting us. A parent is much more capable of deciding what their child is or is not capable of handling.
