Eyeuse2badub, the only thing I would add to your excellent post is this:
Since the 1870s to the current year, the overwhelming majority of leaders/governing body members have been American born and bred with a striking absence of men of color (with 1 exception - but he's American too!) men from Asiatic and African backgrounds and aboriginal men.
At the top it looks mighty white but as you go further down the ranks, you see disproportionate numbers of people from non-American backgrounds.
So very typical of American religious groups.
