So the rationale is that if you want change the first thing is to identify what needs changing. If you want changing in the world of international banking, you should understand the world of international banking, right?

Now, that does depends on the level of "change" as revolution can simply ignore the current state and wipe the slate clean, but I would imagine that understanding how the system operates is not a waste of time if you want to change the system (and not remove it).
