A powerful patriarch/matriarch must choose an heir, pitting siblings against each other in a zero-sum game for power, approval, or money. Classic Example: Succession (HBO), King Lear . Why it works: It weaponizes parental love. The parent claims to want the best for the children, but the structure forces the children to betray each other. The complexity comes from the fact that the children often crave love more than money, but have been conditioned to express love only through transactional dominance. Key Dynamic: The "Golden Child" vs. "The Spare" vs. "The Black Sheep."
