But as far as overarching true things, one of them is, someone needs to take care of children, and families with children, even older kids, need at least some flexibility with work. For a number of reasons women may be more likely to end up in that role than men,
Could you expand on the 'number of reasons'? I'm struggling to find any valid reasons why this is likely to more often be the woman than the man (single parents excepted, obv ). I know how it can happen in practice, as happened with me and DH - but it wasn't a good thing.
The most basic reason is women get pregnant, and I would add, breastfeed, though they don't need to these days. But many people think it's best for the child and want to.
So you already have women who may need to slow down and take time off during pregnancy. Who will probably want time off work in infancy, and will certainly need some time for physical recovery. In some cases this will be longer if there are issues with mother or child. For every child you add more of this time, and it can come to constitute a significant amount of time.
Something that doesn't always get talked about is this all is exaggerated in some types of work. If you work in an office, your pregnancy doesn't likely preclude your normal work. When I was in the army though, I was not able to take certain courses I needed fr promotion while I was pregnant. A lot of heavy work, dangerous work, or work with certain chemicals and things, is like this. Not many women at 8 months pregnancy are going to be working on a fishing boat, for example. So that is a good six months beyond maternity leave where they may not be progressing the same way, or getting the same experience, or even working at all in a few cases. (Add to that, these jobs can be well paid ones because they are dangerous.)
So just as a result of the physical implications of preganncy and infant care, women often will be the ones whose work and career would be affected. Which means the man's career may well be more stable, or likely to progress more, or better paid.
My job in the army for example was not, as a matter of policy, affected by my pregnancy, and they were pretty careful about not negatively treating women on maternity leaves - and men got and took good parental leaves too sometimes. But I couldn't take that course I needed - it wasn't safe - and I couldn't be promoted without it - because it wasn't safe. I have four kids - that was always something that was going to have a significant career impact and meant my husband would likely earn more. At which point, it did not make sense for him to leave his stable, well paid, more demanding job, it made more sense for me to be the flexible parent.
Aside from that, I think women are probably somewhat more likely to want to do that, compared to men. The mother child bond in infancy is pretty powerful - I've known quite a few women to plan to return to work, but who rethink their priorities after being home with an infant. I don't think that is something that we have some sort of moral or social obligation to discourage.
