I don't know. But if they did they could have the same result! Humans don't do well with power. I remember I to felt that power. I was working with an indigenous oil and gas company. And was about to have a huge payday when it never happened.
That little taste of power corrupted me! Lucky for me the Canadian government will never allow the indigenous to sell their own oil and I stayed poor. Now I am based in natural law and sovereignty and learned my lesson. If I ever sell our oil I will not be corrupted. My money will be used to generate local economy, through the use of our most beloved Made Beaver (1820)
