There are a few people in charge, they just don’t advertise the fact. Similar how the ‘Never ascribe to malice that which is adequately explained by incompetence’. These both appear correct to the vast majority of people because of the Pareto distribution of outcomes, the vast majority of people experience the incompetence / no-one in charge and don’t experience the relatively tiny number of events when the competent malevolent people in charge do make their decisions. Consider if you were hosting the Jekyll Island meeting, how many people of what caliber would you invite to be there? And that’s just one of the meetings we know about. Another good one is the involvement of Bohemian Grove in selecting Ronald Regan to run for president. Their motto, "Weaving spiders come not here", like many institutions, describes the opposite of what actually happens there.

No need for a formal command structure when everyone's interests point in the same direction. Self organisation will occur readily enough.
