This just happened in CA! LΑSΞRS, MICRΟWΑVES and D.Ξ.W.s…Oh my.
No one is really at the top of the pyramid in terms of power and control. Balance of interest is always required. People / groups that are not at the top can exert significant power if they control certain key resources that can be used as leverage. But if you really want a ranking and find out who's at the top, the person you are looking for is definitely not a public figure.
