Eh?
Why do they need understanding of the outside world? Do *YOU* have an understanding of the outside world? I certainly don't, since it varies so much from place to place. I'm struggling to understand my own world.
Chimpanzees don't have anywhere near as many tools as these tribes of peoples. Chimps use sticks to get out fire ants and stones to open nuts. Not exactly 'tools' by our standard. Chimps don't make tools, they just use existing stones/sticks as tools. Primitive human tribes make their own complex tools. Heck they build homes so I don't see how you can compare them to chimps.
Sure, they don't have medicine, but look at the health of most westerners. We eat so much shit from places like mcdonalds and then pump ourselves full of anti-depressants, painkillers and all other drugs. We're hardly living in some medical eutopia here. About the only truly good medicine we have in the west is antibiotics, antiseptics and anaesthetics. Most other crap just creates more problems than it solves.
No proper housing? As in what? The crack houses that many live at in the west? Their housing provides them with what they need to survive.
Cave man like grouping? Are you completely uneducated? I doubt you even have the slightest grasp of anthropology. You're just quoting random crap based on your "tv education". What is 'cave man like grouping'? They just look like a bunch of humans to me. Their 'grouping' is no different than any group of people you'll find anywhere in the world. Especially when encountering something scary/new/intriguing as a group.
But gosh, you're right. We should SAVE THEM! Let's give them cigarettes, drugs, mcdonalds, prostitution, disease, crime, pollution.
Go and take a look at Nigeria and the result of what the invasion of western money/oil has done there and see if you still think these people need our "help".
