The Kayan (aka giraffe people) in Thailand are actually not from Thailand, but from Myanmar, fleeing a civil war in their country. In Thailand, it’s apparently better, but they aren’t able to get Thai citizenship and have limited access to basics of modern living, eg. Running water /education etc. There’s been a lot of news reports telling people to boycott visiting them, saying that its nothing but a human zoo- but that’s not the best solution, since they rely on tourism to make a living. Visiting them actually gives them a chance to share their culture with the world, as well as practice their traditions and earn some money. The best solution might still be to visit and learn from them (respectfully), and make sure that the money you give benefits them directly and not just to the tour company.
