I have a theory that it comes down to women's biological clock. They know they will only have the option of having a child between certain age ranges (ideally) and that's close enough in the future to plan for. They need good grades to get into college, they need college to have a career and establish themselves before they hopefully find a partner and have a child around 30ish? Might not go according to plan, but it's a template of sorts. Men really don't have anything like that, in the past perhaps there was, an expectation of getting educated and established by a certain age in order to attract a wife and provide for her and the family. I think it probably leaves some men unanchored with no real direction or ambition, no clue even what they should do.
