Eating the bigger fish won’t make smaller fish bigger. Putting a glass ceiling above the people above you won’t stop you from hitting your head on a glass ceiling. Bringing others down won’t help you ascend.
Big fish eat little fish. Little fish don’t want to be eaten. By keeping the little fish safe, the big fish starve. All you need to do to make all life fair in the pond is to protect the little fish. Preserve their freedom.
Attacking big fish is only a distraction—such an effective distraction that provoking attack could be a big fish tactic.
