Nice concise article - much of the best information is in the comments.
Now when the bubble bursts, as it will inevitably, some hedge fund that caused the problem, and that made gazillions when they got in and out correctly, that is going to get burned by holding futures when they plummet downward, is going to jump up and down and scream that they are "too big to fail" and we, the taxpayers who got shafted in the first place by paying artificially inflated prices, will be asked to bail them out so that we will be shafted again and the funds will suffer no fiscal punishment.
Heads they win, tails we lose.
