Let me give you some facts:
Most of the hilltribe families live in remote upland areas where the nearest school is 10 km away. They dont' have the time or the means of transport to deliver their children at school. As a result, their kids work with them in the steep mountains to gather some food or stay at home alone with no meals all day long until their parents come back home in the late afternoon. Every day children in Northern Thailand are being orphaned by AIDS, disease, accident, abandoment or suicide. Many of them choose drugs and alchool as their best friends. Many children are being sold to the pirates - people who would give you money for your 7 year-old daugther to "take charge of her" and "give her an education". What really happens is that these girls are driven to some big city, put alone in a locked room with no windows for two years, serving 10 to12 customers a day. The men do NOT wear condoms because the competition is too great between the brothels and the friction wears sores on the girls. They will eventually get HIV and are beaten if they protest. After 2 years they are allowed to work alongside other sex slaves in the brothels and are watched very carefully. This is however the worst scenario.
