In modern urban culture finance and the law become increasingly complex. The way to make money in both these areas is to find loopholes in the regulations. Those with a better tolerance of complexity will succeed. They will regard increasing complexity as a benefit as it sorts out the players from the amateurs. By business-evolutionary pressure the peculiar aspergery/dedicated/creative combination needed to flourish in complex regulatory environments will further encourage complexity in that area. The complexity handlers will be vastly well rewarded, the rest will get little. A priestly caste will emerge, albeit one which is not hugely difficult to join if you have the right mindset.
But since this is a positive feedback situation the only brake on complexity increasing will come from outside. A Gordian knot solution (Alexander didn't bother to try an unravel the impossible knot, he cut it). In this case someone with a gun takes over the land and resources of the complexity masters.
Or is there another ending?
