I concur, but do have a quibble.  I am not sure if it's helpful to say they coordinate. It an active interaction and plot. I don't think this is the case and if the rules require that you uncover and price that, it is unlikely to ever happen. But in markets with less competition, it is easier to, for lack of a better expression and to steal a line from Adam Smith, have an invisible hand guide them to uncompetitive behavior that mimics deliberate and active coordination. To the players of seems like they are competing and they mostly believe they are competing, but it is not the kind of competition envisioned by economic theory, so it does not help with real and original innovation or price competition (meaning something like price equals marginal cost in economic speak). The Colleton bureau is corrupted. By that I do not mean dishonest, they simply have a distorted view, on practice at least, of what economic competition really is.
