upper class women have more to gain from academic education and could use surrogates to keep up a birth rate without committing career suicide
There are more normal (i.e. less Brave New World-reminiscent) ways to make it easier for people with a career to have kids (though of course the future needn’t be normal) -- paid maternity leaves exist pretty much everywhere in the world except the US and so do paternity leaves in a few countries, France has a 35-hour working week and the sky hasn’t fallen there, etc.
while lower class women would be happier without being forced into the workplace and would contribute to societal stability
Before solving this problem, shouldn’t you ask who is doing the forcing? It’s not like being a stay-at-home mum is illegal, so why are they working outside the home for money if they’re less happy that way? Once you answer this question, then you can think of possible solutions. (The reason for poor people may be different from that for rich people, and the solutions that would most help the former may be quite different from the ones you’ve thought of so far.)
The main thrust is this; if there is a .33sd gap in general, and a 1sd gap on spatial relations specifically, and men have wider variance at the edges, then why should we expect anything but inequality in fields which rely on exceptionally high IQ and solid spatial reasoning skills?
On the other hand, on fields that require average-or-higher (but not necessarily extreme) cognitive skills other than spatial ones, we would expect inequality the other way (and in some cases that’s what we already see, most school teachers being female); do we really want most of those people to stay at home because of social norms that developed long ago, when said cognitive skills were less important than today and manual labour more so?
