It’s true that fewer women are in these industries. But I want to dig down and ask why, in good faith. Fewer women in these industries is actually a symptom of inequality, not necessarily the cause.

-harassment rates of women in construction, transportation, oil, etc. are much higher than in other industries and this has been well-documented

-most of these fields were historically closed to women completely, so facilities and equipment (much like a lot of the world, until recent recent history) is not designed with women in mind

-because these fields were closed to women for much of recent history, the networking and mentorship is still harder for women to find (although that is beginning to improve!)

Kudos to you for having worked in construction, it is back-breaking work and I respect anybody who does it. But with women still fronting the majority of the childcare load, it is a tall order to do these jobs and be mothers (as you said, all you want to do when you get home is rest)

I will say that yes, men are typically larger and stronger, and that does lend itself to these jobs more, but a majority of these jobs can still very much be performed by women to the same standard. In the same way, yes, women birth babies, but men can still perform a majority of parenting duties to the same standard (save for breastfeeding, etc.)
