@mhercigurl The men you want to marry have realized they don't have to, the men who would still marry you have decided that the women who are still available are not worth it, and men who understand they don't have much of a chance with the women who are left have made their peace with it.
@pinkleftygirl Men value youth, beauty, fertility, and agreeableness/cooperation. When you see it through that lens, it makes much more sense to try to date a twenty year old woman than a 40 year old woman.
@travelingflying Most men do not care, because the broke ones have nothing to lose and the wealthy ones will enforce prenups. It's the upper middle class that will care because having a wife with a similiar earning potential will typically negate any significant spousal support.
