Such is the natural state of all peoples. That only changed with agriculture enabling the total supply of goods to increase faster than the population. Agrarian peoples (also known as aryans, from the word arya meaning soil tiller) did not live in a zero-sum world like hunters and herders, for them productive activity brought more benefit than theft. The next revolution came during the medieval era in the netherlands, trade made it beneficial to not rob and kill people for things you could not produce yourself. Peaceful exchange avoided costly conflict. Of course, this can also be blamed for the acceptance of outsiders that plagues the west today, but acceptance can be unlinked from cooperation.
Back to injuns, most in the eastern US developed farming, but hardly to the same extent as europeans or asians. They still depended on hunter-gatherer skills and retained the savagery of primitive tribes. This was more true the further west you went. Obviously without large scale agriculture or trade there was no record keeping and thus no writing. We frankly do know much about the pre-1500 Americas. It can be said that many British regarded the natives as lost Whites. While they are closer to the British than negros, the natives were clearly not White. The British could have easily exterminated them all after a few decades of settlement and did extract harsh punishment on even perceived crimes committed by natives, but genocide would have been more trouble than it was worth and it was often easier to buy land with a few cheap beads or alcohol or something. I imagine it is much the same way we would be treated if aliens colonized earth.
