Not just executives, a majority of non-leaf nodes (but not all). The more money that's at stake, the more petty and childish people act. Acting like a child is an actual strategy people use. If people act rationally it provides a stronger basis for criticism and makes them a target. If someone acts like a child then people say "wow that person's a real stupid jackass that only wants power." If someone tries to rationalize bumping off their competition, its "wow that person is a real threat."
