I've taken an incredible ration of bad commentary over my half-dozen or so articles on the oil glut's impact on the economy.
But one constant remains, the economy as a whole is still not benefiting from the lower oil prices -- the stock market continues its slide, the Fed chair issues new warnings, and some speculators are even predicting $10 per barrel of oil.
Why has this glut continued for so long? Four reasons are keeping it alive and well -- and have placed oil producing nations in a position where they can't collude on production amounts to prop up prices.
