It's common to believe that natural selection leads to an efficient effective result. This is a false and inapplicable. In the first place natural selection just means that the least defective, insofar as survival is concerned, changes that randomly occur pass on to the next generation. There is no guarantee of forward progress along any axis.

Secondly a human power structure a created thing needn't follow any such law. Success in society often depends more on perception than any objective measure of success. While bad decision making can put one out of business eventually there is no guarantee that the ones that follow will be more rational.
