I'm still inclined to the view that banker behaviour imitates predation, though
a formal and irrefutable proof would be difficult to prepare. There are significant
similarities in the behaviour of parasites and predators, as shown by this paper:
http://www.blackwellpublishing.com/pdf/42-3-pp-693-726.pdf
thus it is conceivable that in some specific conditions, there is no difference
between predation and parasitism.

In defence of my view on banking predation, admittedly a single instance -
the banking predator is discussed in the second half of this Max Keiser show E593:

Just a fun comment: If you can see a parallell between a fox acquiring the keys to the
henhouse from the farmer in exchange for a handful of counterfeit notes, we are
definitively talking about predation by the bankers.

If you have a particular argument for parasitic behaviour, I will be interested to
read it.
