What is glamorous in middle school and high school ? Well, the jobs the people "in power" at such institutions have, and in their own families. So Mom's job (the carer's job, because most families have a carer and a provider or at least have those roles be unbalanced and of course most contact will be with the carer, not the provider). The teacher's job. Caring jobs in general. And of course the "in power" jobs on TV. Men are immediately discouraged from doing that and so they skip ... what of course turns out to be mostly undesirable roles. Which make these women easily exploitable, and perhaps there ought to be some discussion of why that is such a big problem for anyone.
Maybe what needs to happen is we need to start telling women of age 10-12 "you know, in 10 years, a bit more, you'll need to support yourself, maybe a family. And as a teacher, carer job, or mom, it'll suck. You'll be low on the scale, and dependent. Think about it now and save yourself a lot of pain later".
20 years later (because that's how long it inevitably takes) we'll have a majority women, because they really do outcompete men on average given the chance. I mean, I do agree there's no way in hell this will ever happen, but one can dream.
