There is an interesting documentary called "The Norway Paradox"[1] that explores why do we see a much higher rate of gender segregation in developed countries. The thesis the documentary advances is that there are indeed innate differences between the sexes, and with higher freedom that can be found in advanced societies, the people are freer to choose a job that fits their innate tendencies rather than be forced into something else by economic or social circumstances.
Another video worth watching on this subject is the debate between Steven Pinker and Elizabeth Spelke on The Science of Gender & Science[1] which was held in the wake of the Larry Summers controversy at Harvard in 2005. They both make many good points, and it is clear that while discrimination exists, it is probably not adequate to explain outcomes which are aligned with innate preferences and distribution of specific skills.
That question appears to be addressed in the post to which you are responding. I won't be as bold as some to lay causation purely on biological differences, maybe there could be some factor we're not accounting for on why socially flattened societies tend to have larger exaggerations in traditional gender roles. However, if your policy platform wants to push equality of outcome for career paths on the sexes then this deviation from expectation should be disconcerting.
