The opening paragraph of this article bears careful reading... "Complexities come with an insidious burden and blindness that human nature oddly finds attractive. Complexity is often equated with sophistication, however, erroneously. Complex objects, ideas, and systems tend to elicit awe. Complex problems tend to be treated with complex solutions."
There is an axiom in military planning that warns against complexity. "All plans are good until the first shot is fired." Keep it simple, stupid, and allow subordinate leaders to adapt to the situation on the battlefield.
Still, complexity does appear attractive. Well, it certainly does to those who wish to commit crimes. Take, for example, the propensity of progressives to complicate the Constitution. Why would they prefer that to the simple, plain language in which the Constitution was crafted? Simple. Look at how they've been able to mutate our government. It little resembles that blueprinted in the Constitution.
With this warning in mind, read the linked article if you have the time and inclination and then ask yourself, what sorts of nefarious deeds may we expect from financial and government leaders in such as complex system as described?
