If they admit to hypergamy, men will not want to simp and dedicate their lives for them. The free meals and gifts are gone. The rent free life courtesy of their live in bf or husbands are gone. The widow benefits from their law enforcement/military partners are gone. If men know that women in relationships tend to monkey-branch, they won't date them. If men realize that they marry with the plan of divorcing down the line for cash and prizes, no man will want to commit.
