One of the most powerful native americans in history thought he was the richest man in the world; and that was before coined currency even found its way into his hands.
When it did, he turned around and gave it back to those who he saw needed it more than he did; as he pitied them for their lack of functionality and priority.
He could walk out into the middle of the battlefield, sit down, smoke his pipe (as bullets were flying all around, and at him) til it was gone, then get up and walk back to where he came from unscathed; knowing full well that he would not be hit on that day.
The original/true medicine men did not work for money, they only worked on healing people at no charge; and their people supported them for doing so.
