Camps around Thailand regularly take in children who are orphaned or who's parents can no longer afford to raise them. They are trained from as young as they can walk and are fed, clothed and provided an education by those who take them in. In return, the camp typically take half of their earnings. Not all motivations are monetary in nature...in these examples, the welfare of the child comes first and they are taken in because they have nowhere else to go. This is their only path to a future in which they can find survival.
