He may have gotten a bit more than you in a worldly way, but he is still Native, whom most of those afflicted with 'white privilege' look down upon or are ignorant of. White privilege is not that you have more privileges and perks than others of other races, but that your people don't understand the nature of 'white privilege', the inherent racism of things. Blacks try to share it too and are often ignored or ridiculed for it. 
Let me give you an example, i was working on a hot tar roofing job in Anchorage, when one of my uncles, who was drunk at the time, happened by and saw me. 'Hey Christ...!' he shouted to me, waving with his buddies, all of whom were pretty sauced for the middle of the day. I returned his wave and went back to work. That evening I was fired. I had done nothing wrong, had not been admonished for any poor work or told I was lazy or inattentive. I was fired because they recognized I was Native after that incident. Nothing more.
