Child Labour

People talk about the child labour on different occasions. But how they missed this?

Normally people point out the poor kids working out some where to earn few bucks for their daily breads and force them out of their job. This might make their life more miserable. Why those folks look at the above advertisement. All the actors in the above advertisement are kids. Is this not a child labour? Why nobody argues against this? If we stop this kind of child labour, it will be better instead of stopping the child labour that is required for running the life.
