That being said, I think we should generally imrpove sexist behavior and systems, which hurt both sexes (albeit, in different ways).
I just think the "wage gap" is one of the least sexist fascets of modern society (if at 3-6%), and mostly represents people perpetuating a misunderstanding of statistics. So in that way, I feel like people are over-solving a mostly solved problem, which seems likely to lead to more sexism, not less.
I think that effort spent on fixing the larger issues are also likely to stabilize remaining issues with wages, and we would all be better served focusing on the large gaps in other statistics instead of the small one here.
That said, Im always happy to see new statistics that tell me Im full of shit, so if you find what you're looking for, please post it.
Otherwise, have a good night! :)
However, there is abundant evidence that there's a systemic divide in opportunities. This is easy to see in the aggregate and particular. That is the interesting thing in itself: if we could be assured that the gap could sexist solely for life choices, this wouldn't be an interesting topic. That's a devilishly hard thing to argue for, however, so id prefer to move forward as a society assuming that we can do more to expose opportunities to everyone, assure that people are protected in their right to follow opportunities, and that we can demonstrate the effect of the policies at moving toward an ideal of equal pay.
If we can't move towards that, perhaps our ideal, well, isn't what society wants. I doubt that we've even approached that level of confidence in our support of communities subject to subtle bias difficult to divorce from "life choices".
