This is just common sense, or should be. Unfortunately common sense is as uncommon as people tend to joke about. So you get a lot of focus on business hiring practices, even though it's literally impossible to hire candidates that don't exist. Sometimes this gets taken to absolutely farcical levels. I recall reading a blog from an Irish writer about how activists were trying to demand that companies there hire black people at such a rate that there literally are not enough black people in the country to meet that quota. And yet, this sort of brainless activism continues unabated - why I can't begin to guess.
I do think that trying to shape job demographics is misguided. It doesn't matter that we get more women in tech, it doesn't matter that we get more men in nursing, and so on. What matters is that the fields are open to anyone with an interest, not the resultant demographics. If people aren't interested in those careers, that's perfectly fine.
