One of the main points here is that the highest level of the hierarchy is simpler to model, and even simpler to understand (for those who honestly assess the data). This is why so many people work at unbelievably complex tasks, propping up the simple "higher-level" goal of theft. The area where most people fall down is in seeing the hierarchies they are a part of.

Kind of like the trunk of a tree being easier to model/simulate than the branching root structure that lies below it.

Anyway, thanks for the comment!
