There's a lot of effort going into this, actually. My father was a nurse for 30 years and in his nursing school graduation photo, and his retirement photo with his colleagues, he was still the only male. It's possible men view these fields as female dominated and resist applying. It also raises the awkward question of how men are treated in female dominated fields. Would a man be treated better in a female dominated field, than a female in a male dominated field, or the same? I've not seen research on this, unless someone knows of any?
Exactly. No one's worried that we have too few female coal miners or garbage collectors. These are physically demanding, not prestigious and often low-paying jobs.
Hell, no one's worried that we have too few female oil rig workers and these ARE (in my understanding) high paying jobs.
If you talk to men who worked as primary school teachers (within the last 20 years) and then changed careers, you'll hear a lot of interesting stories of discrimination.
There were more men in these roles when it was more respected and well paid. As the relative wages and notarity declined, men started targetting ‘higher jobs’
