I think that men and women should consider marriage in their thirties.
By then, the worthless have shown themselves for who they are and in your thirties you’re a lot more intelligent about human nature and the realities of how people are.
A woman who wants to be taken care of will either earn her own way by habit or slip into poverty and a smart man will not marry her and risk losing everything.
As for women, women will be safer since they will have their own money to get out of a bad situation and they’ll be a lot more savvy about the men that they actually choose to mate with.
Some men are attracted to the damsel in distress.
