Here's the peer reviewed article link too: Mating markets and bargaining hands: Mate preferences for attractiveness and resources in two national U.S. studies Summary: Rich women STRONGLY go for rich/"good career" males, Rich men go for slender and younger women. Not too complicated. Ergo, richer/higher income males often DONT value high income in their partner compared to slender/youthfulness likely due to wanting a family from a biological perspective. Women of all socioeconomic classes want men who earn equal or often MORE than they do as a primary motivator for commitment. This correlation is STRONGER for HIGHER income women.
