Interesting piece. Note that there's some empirical evidence to suggest a controlling cabal (I prefer the term "oligarchy" rather than "monopoly"):

The next question is: is this deliberate or an emergent property. I'm inclined to suspect a bit of both. There is a desire to control, but there's also a likelihood that there will emerge some group which has control. Which then raises the question of how to reconcile this with existing economic, political, and social theory (all of which are, I suspect, badly broken and fail to take this into sufficient account).
