CHILD LABOUR.

Everyday in the newspaper we read about the police raiding hotels,shops and rescuing children who are forced into child labour. Recently an article saying the above mentioned was published but the place raided was a circus were the children were made to perform. I ask are the children who are made to perform on TV in various reality shows not child laborers. The children in the circus were artists,performers and so are the one on TV.Even kids in the glam world are made to practice for long hours,go to school and take very little rest. Then why the discrimination?Why don't the police raid studios?
