you assume that organizations with inofficial power webs only have official goals? The inofficial goals might strive very well while the official organisation struggles. For instance I assume even if McDonalds shops struggle financially McDonalds itself is still quite happily collecting rent from them.
Oh, I don't assume that, and you bring up a very good point that goes over most people's heads. In fact, it reminds me of how I learned that most organizations of appreciable size don't care much about efficiency. When things become more efficient, it not only rocks the boat, but people can be put out of work; once the cash-cow has been established, people want things to stay the same, lest they lose access to the udders of said cow. This is despite the fact that such an organization will publicly value "innovation", "creativity" and "hard work".
