Since mamboni's was mentioned as a counterpoint, here's one from him that broke the bank.

If treasures are in a bubble like an engorged spleen, the latter develops pathologic internal resistance to flow (capital), as blood (money/credit) pools inside the spleen (treasuries) in lieu of circulating in the peripheral to supply oxygen to the tissues (small businesses, consumers). FED purchases of treasuries and interest rate targeting (Operation Twist) essentially shunt arterial blood into the spleen, further starving the tissues. The Wall Street banks are blood sucking leeches attached to the spleen. They have adapted themselves as pure parasites and require continuous blood from the spleen to survive. Splenic blood pressure must continually rise (declining interest rates) to feed the parasites. When the interest rate zero bound is reached the spleen has reached maximum blood volume and will either explode/hemorrhage (deflation) or collapse/contract (rising interest rates) and release it's blood into the circulation and cause malignant hypertension (hyperinflation).
