The difference here with what you purport and what Indigenous cultures are experiencing, is that the Indigenous peoples still suffer oppression at the hands of the Euro centric colonial system. All the groups you've cited are white, or could be identified as white, and would have integrated into the system over time based on that alone. No person of color will ever be able to join that club. Basically, society needs to be wholly re-made so that skin color is truly no longer a barrier to receiving the fruits of the current privilege afforded only to those that are identified as white.
