They still exist. Across the world we have many locations(Amazon and some islands) where we have 'quaint' tribes living in isolation, with people from the outside more or less forbidden from visiting them so the rest of the world can still have the wonder of real life tribes living amongst us. The fact there is quite a movement(often amongst the left) to encourage tribal societies to stay technology backwards shows people still think it's ok to keep others as entertainment.
