I have a bit to add if you don't mind about care work and women.
It's not going to be as articulate as I'd like but I'm extremely inarticulate and struggle with getting my point down, but hopefully you'll see my wee theory here. And I'm so sorry it's so long.
For the last 20+ years I've earned NMW doing care work in all its varieties.
I've done work with dementia, end of life care, worked in nurseries with children and spent most of my working life supporting people with autism, mental health issues, extremely challenging behaviour, learning and physical disability. I've been beaten up, spat on, shat on, I've been threatened with a knife. Had to have a tentus for a bite. You get the picture.
So from home help roles to secure units, caring for ex prisoners and child sex offenders, nursing homes etc and my single nvq in health and social care was enough of a qualification to ensure I was able to get those jobs and even if I'd have progressed in any of those jobs there was no further path I could have gone down after the nvq. A bit of in house training every blue moon but FA else.
So anything from holding a persons hand and keeping them comfortable during their transition from life to death which is mentally devastating, from having a lovely day at the cinema with a person who just needs addiontal support in the public, you'd get paid the same. (Pittance) now men who work with in traditional working class jobs (like caring is) such as builders as example, well like a care worker a builder is often able to do tons of jobs under one umbrella, such as joinery, tiling, plastering and will be able to quote you on the hour for what the job entails, so fitting laminate costs less than plastering etc as where women in a predominantly female environment won't be able to say, "Oh you want me to wash 28 stone Dennis who covers himself in shit and has been known to jizz himself during a body wash? That'll be an extra fiver for that pervert, please". (Dennis you'll be thrilled to hear was also an ex headmaster. No dementia, just a horrid fucker who would request the 16 year old apprentices to clean him)
Now why is it women who get paid less in these kinds of jobs?
Care is shit pay and ten a penny jobs and the women I've met in care often fall under the following.
Can't read or write or do basic maths.
Have no qualifications at all.
Need certain hours, such as nights or 8-2 for childcare.
Haven't the confidence when their children are older to retrain unless it's as a nurse - which is also why I believe male nurses seem to get ahead quicker with promotions, women train later in life or they have families that takes priority over promotion.
Controlling husbands and partners don't want them working with men or in public facing roles.
Their mothers did it is a huge reason, especially in nursing homes, I've worked places where a mother and daughter have cared for a mother and daughter resident, decades later.
You can get away with fucking murder in most places and unless you're caught literally commiting abuse, which is rare tbh, but unless you're swindling cash or stealing valuables, there are 100s of ways to abuse people financially, care does attract wronguns as well as the absolute angels.
Women who just love caring for people and just want to do that, they enjoy the job and make the sacrifice of a proper career to be a hands on carer.
Now back to builders, if you're a builder you can have little or no literacy skills.
Math needs to be basic, so measuring is essential and working out quantities, but nothing that is incredibly taxing.
You work school hours and rarely do weekends.
You can progress your career and whatever your specialist skill, so say joinery, you can 100% continue qualifications in that field and become an expert in your craft, which if your skill is palative care, you cannot.
Men can continue career progression with their skills, in a way a women can't and even though society isn't kind about builders (look at the threads here, people hate them) they're far more valued and given more opportunities than carers ever will be, purely because one is a male dominated industry and the other is female.
Women can't progress in industries they dominate because we don't give them the opportunity. We're expected to stay low level plebs in poor people jobs with no genuine teaching of skill etc when people dealing with death regularly should be rewarded financially and trained with very specific ways to make the person dying feel as relaxed and at ease as they could be. If we can (and rightfully so btw!) Give a time served tiler more credit for his skills and pay him well for his experience and well delivered service, why the fuck can't women get that also? Our skills matter, our experience matters and what women do should be recognised with a merited qualification.
