If I had a DD I might well, depending on her aptitudes. Working in the trades can be satisfying- there's tangible evidence of your work- flexible in the sense it's a job you can travel with, and well paid.
I work in a....kind of trade, although it's regarded as pretty niche. I certainly get more men on the sites I work on staring at my work admiringly than they do my arse 😆 (but I am in my 50s, don't know how much grief a younger woman would get). It's actually a very female dominated trade, which is interesting- I put it down to the fact that it very nearly died out in the 1980s and then got resurrected by hipsters, so the culture of male gatekeeping had died out in this trade. It certainly shows that it's the kind of job that women want to do when they're given a chance to!
I recently spent a month or so working on a busy site with dozens of construction workers coming and going, and in that whole time I saw two other tradeswomen- a joiner and a gas engineer. I think the reasons why are complex, and down to a lot of subtle and not- so- subtle gatekeeping from the men. Basically, they don't want the competition for the jobs. It's not really overt when you're on site (again though, I'm middle aged- whether they'd attempt to mess with a younger woman I don't know) - builders that I've seen don't spend all their time being gross or sexist or laddish, 95% of their conversation is bitching about their colleagues or trying to work out who's taken their drill without asking 😆
My assumption is that small/ medium sized firms aren't taking women on because they don't want the competition, that girls are being vibed out of even going into the trades by the general attitude of gatekeeping, and that the women that do go into the trades aren't often seen on sites because they're so much in demand from female householders.
One thing though- I do think that the strength thing is a red herring. Female carers are often expected to lift large adults on their own, and this is seen as normal. Plumbing, electrics, painting and decorating, tiling and many other trades don't require brute strength, and even as a not- particularly- fit middle aged woman I can wrangle whole sheets of plywood just fine.
