According to this sub, most men have lower standards than women. Although I think they have standards in different ways to each other, I don't think it's completely true that men as a whole have lower standards for women.

Since hypergamy can't be avoided, surely the ideal situation would be one where the woman feels like she can't do better than the man. Then why is it that many women feel unsatisfied with their partners? Surely if men were lowering their standards where only an above average man could obtain an average woman, then the woman should be satisfied in the partnership.
