I just read an article the other day about a woman who thought this was a clever approach, but later, when she tried, all her eggs failed, meaning she essentially paid to lose her chance at reoroduction. If we encourage this as an option, then we will see more women trying it, with some portion of them successfully reproducing when they would have succeeded anyway, and some portion failing where they would have succeeded. Accordingly, this sounds like an effective way to further decrease fertility while also increasing its cost.
Society might be wise to simply be honest with women: the overwhelming majority of "careers" produce little lasting value for society in comparison to reproduction, and doubly so for the sorts of careers educated women often pursue. If you enjoy being an H.R. manager, or a social worker, or a psychologist, or a lawyer, or an anthropologist, or whatever, then that's fine, but society would gain more in the long term from you simply staying home and propagating your genes than from whatever H.R. policies you'd push at Wells Fargo or whatever. There are exceptions, but they are rare enough to be not worth configuring social messaging and culture around, especially since the exceptions will probably just ignore the messaging and culture anyway.
If her eggs fail, have not you heard about egg adoption? Another high IQ woman who has ten frozen and may need two or three, will donate.
About jobs. Women control fertility now. They know the allure of having own job (which soon will be paid at the same level as a guy's one, thank god) as compared to sitting at home, waiting for "the provider" to come back. And let us be honest, a one-income family economically is rapidly sinking pretty low. So instead of having three kids, renting a house and sending kids to a school in mediocre neighborhood, the woman thinks, OK, let me have one kid but provide him with as much as I can. So that he does not complain that he has no money for college.
And also - how about talking a woman into producing kids and a man, her partner, into sitting at home and raising them? Both propagate their genes. It is unfair that a guy gets the chance of career advancement and a woman is merely changing diapers.
P.S. two more points. The most recent study about declining birth rate was done in Oregon. Women there specifically mentioned not being secure in the future.
Now, what would a high-IQ university grad woman do with Oregon job market? She could move to the Silicone Valley where marriage market favors women and marry a high-IQ-IT guy who can provide for her kids. She'll mate her DNA with his DNA, and at least there will be the incentive to leave the posterity as guys there are paid well. So I think there will be tiny enclaves where fertility rate will be at least at sustainable level. But - women with high IQ want to live in style, and I don't blame them, so these will be the places with stable jobs.
(And deserving men). When Brandon Tarrant complained about white women not reproducing in his manifesto, I thought, he was one of the prime examples why! A guy without University degree, a gamer without a decent job that could provide for the family, investing inheritance into traveling but bringing back killer's ideas and some weird imaginary world, total waste of society's resources, what university graduate woman would want to reproduce with him, sorry?
