Thanks for your remarks teageegeepea.

There is a difference between modeling and manipulating.

To model, is to create a framework that describes something.

To manipulate is to choose one or more elements among the known attributes of the model which can be controlled and then use that to coercively accomplish goals; then set the model up to "show good things are happening" based on the all wise management of the modeled system by the managers.

You note "a significant degree of accuracy". The point is that the degree of accuracy that can be attained is insufficient for the purpose.
