In 2009 Anglo-American empire (I added Peru and S. Africa to this camp) produced 61% of official global gold. In 2011 Anglo-American empire (with countries like Morocco and Papua New Guinea counted in this camp) produced 58% of global silver.
What I see here is that the Empire does not control anywhere near 100% of either metal. These numbers tell me:
We’ll ride the oil and oil-tied fiat train until it stops.
Then we’ll switch to bombs to grab whatever we can.
Then we’ll sort through our loot and see what it is that we are the world’s largest holders of: gold? rubies? copper? timber? pebbles?
We’ll make it our new currency.
Until then, oil works just fine for us.
