As recently as 1970 women in the US weren't allowed to open checking accounts or get loans from a bank by themselves, but tell me more about how no one _ever_ stopped women from doing what they want.
Well, based on studies I have seen, if the family had only one computer, it waay often in boys room rather then in girls room. PC was assumed to be boys toy.
The culture emerges from there.
Anecdotally, that is patter I do see around. Parents of young girls are way more often enforcing "no screen till this or that age" while parents of young boys almost brag about boys playing games on them.
Maybe boys get more screen time in families like that because they're more interested in computers? Maybe it's assumed to be a boys toy because boys show more interest in it?
i.e, the banking situation you mention was not a barrier to employment whatsoever.
