Nope because during the 1950s-60s not many women were even interested in those things. Even if they were still allowed to join back then they'd still be the 1%.
So is the massive surge in female interest in engineering because of magic, or because there aren't impassable institutional and societal barriers blocking them from pursuing that career?
So if you were designing bridges in 1950-60 without a degree you now can't prove you have the knowledge since degrees are a requirement.
That's because you shouldn't be planning out a bridge unless you went to college for it. Building bridges that don't collapse requires physics, materials science, CAD skills, and a whole host of other stuff that you can only really learn by going to college for it.
Trust me when I say that we'd have way more bridge collapses hiring promoted construction workers instead of all-female teams of degree-holding engineers from accredited colleges lol
