I know you like to portray yourself is some big shot business man.
Let me put this in simple terms for you.
If OPEC wanted the price of oil at $100 a barrel by the end of the month - It would be at $100 by the end of the month.
They even employ brainy people that would tell by who many barrels to cut output.
Don't know about your world - But in my world that is the very definition of controlling the price.
