There was a fundamental difference in the way that the Europeans and the way that the Natives viewed land, the former believing that one could own land and once owned the resources of it belonged only to the owner, and the latter believing that ownership of land was impossible and that it was there for the franchise of anyone who needed it. So, according to history, there is truth to the idea that the natives shared and the Europeans did not, but the oversimplification of the issue and neglecting of the inclination towards warfare that most tribes had is moronic.
