It's quite simple. This market is manipulated, and markets cannot be manipulated for too long. This simple fact has been proven over and over again. Those who deny it, will live to see the day when they are completely wiped out, financially.
I have worked with banks - they are incredibly incompetent. Think "Three Stooges". For them to pull off a concerted yet secret plan to sequester away property in order to control the market is pretty close to laughable.

Define "too long". I say that because DeBeers has been sucessfully manipulating the market for 60+ years. The US govt has been sucessfully manipulating certain commodity prices for nearly 80 years. Is this not "too long" in your book?
