Yes. But without the discussion of all the ins and outs then it just comes down to a misused statistic. Which I think is the point you are kind of making anyway.Yet, here we are, 40 pages in, going around in circles, the amount time and emotional effort to keep the narrative to 'there's a gender pay gap', without the nuance, like it's an everyone's / whole of society's fault / problem, is staggering, but I suppose I shouldn't be surprised.
It is interesting that this particular gap is highlighted and pushed hard. There's many other ways to slice and dice society and look at the pay gap. Disability would be a good one to look at - particularly where the disability does not inhibit the job. Another really interesting one is height - I remember reading somewhere that if you exclude all men over a particular height then the gender pay gap becomes very minimal.
Then there is ethnicity (both in looks, behaviour and name), suburb you live in, school you went to, all of that stuff.
