@jrandom42 simply put, in many places still [from my perception], it's a "forced transition" based on social expectations. Superb management skills notwithstanding, I detest the *idea* that if I ever marry (which seems unlikely at this point), social pressure in such places would tend to want force my wife out of the workforce because
obviously now her
job is "make bebes".
Yeah, continuation of the race is important, but if she *wants* to do something else than look after the house and the kid(s) after they're of school age (or, as a thought experiment, consider that WFH is starting to sound less and less stupid - permissive WFH schedules would allow such career-driven women to continue their careers without the perceived-by-so-many-others issue that she's a mum and therefore can't be relied on because she'll leave at the drop of a hat because bebes/kids), then in many parts of the world, it's a hell of an issue just to jump back into the workforce.
Again, this has nothing to do with management skills (which kudos to your wife if she's that good and beyond, give her my regards), and everything to do with [my perception of] human morals not having progressed as uniformly and as quickly as our civilization development level over the last hundred or so years.
