Who are the 'wild men'?

Were they squatters or were they the closest we could come to the original inhabitants of the area?

By contrast, the armour of the Men of Rohan was made for them by the Men of Gondor. Presumably when the Dwarves lived in exile in Dunland it was to avoid, in their pride, having to live in the lands of other "civilised" people. Instead they retreated to a lightly-populated area (Dunland does not seem to me to be a very densely populated place) and perhaps had little to no contact with the Men in the vicinity. Then again, I can imagine that they probably traded with the Dunlendings for food, but probably did not trade weapons or armour. Dunland was perhaps a place where they could live in some peace and quiet and trade for their survival without the "shame" and (perceived) indignity of living such a life of exile among more "civilised" people with more established homes.

It seems to me that somewhere Dunland was described as having little in the way of mineral resources, but I can't seem to find it. However, if that was the case it could be that was the reason why. The Longbeards may have gone there to try to start fresh with some nearby humans (a method that had worked well in the past) but the colony failed because of lack of mineral wealth and so the Longbeards moved on.
