The capitalist class.

> Do they meet over brunch to plan it?

Sometimes. Sometimes dinner. Sometimes drinks. Sometimes, at meetings of the global institutions they and their paid agents run.

Not, like, in one unified, organized group, just a disproportionately powerful class, with many members aggressively pursuing their own self-interest, and coordinating on that where they recognize the opportunity.

The same way they overthrew the feudal order and established the capitalist order in the first place. (And also the same way that the larger but less disproportionately powerful classes beneath them have weakened the capitalist system in favor of modern mixed economy as the dominant system of the last century. Which has a lot of the first group irritated.)
