What went wrong?

Well, since the economics blogs are on the subject of what was done to quell speculative excess in the 1930s, the "800 lb gorilla in the room" happens to be Bretton Woods. Why? What led to derivatives (recently rightly referred to in Congressional testimony as the latest incarnation of Bucket Shop practices) engulfing the world monetary system? It was none other than the end of the system of settling imbalance of trade among nations in gold. After the Nixon administration pulled the plug on this in 1971 the scene was set for a global casino of currency speculation. One bubble after another was created and blown out. Now we are at the point of either attempting insanely to further hypothecate our economies or to return to the Bretton Woods system of stability.
