This paragraph really says it all re the Opecker Princes of Opec: Ebel said: "The fundamentals are really the same as they were before. There's no shortage of oil out there that I know of." [How to raise prices, pay Yassir to turn up the heat?]
Basic economics 101, a cartel is needed to creat artificial shortages of a commodity/product where there are no shortages. OPEC is the classic example of a cartel that has been creating artificial shortages since the 1970's!
