Saschabr,
An 'invisible hand' effect ensues from the cooperation of individuals in a collective endeavor. Let's say, the futures market. Everyone is, more or less, acting in their own self interest. As the market filters these motivations price fluctuations occur. Some individuals, who have correctly understood the market dynamic, profit from these fluctuations. No one knows, exactly, what will occur. Because what occurs is a product of all participants. This is the invisible hand.
The book, "High Treason" pulled several conspiracy theories concerning JFK's assassination in Dallas, TX, together. I read the book. Knowing the truth, or even the part of the truth that book exposed, has made me no freer today than I was before I read it. The same is true of your market manipulation theory. I admire your ability to think through the scenario and to expose what may lie behind the 'official story'. However, as has occurred in the past, the official story is what most participants will read, laugh about, and forget.
