One time in a DND game I had a dungeon with the property "you'll never find what you're looking for". This has a bunch of fun effects. Among them when the players found a spiral stairway around a hole, they tried to find the bottom and, because of the rule, could not reach it. They tried to go back up, and couldn't reach the previous floor either.
So they decided, since they have feather fall, to just jump into the central hole and find the bottom that way.
They fell for an uncomfortable long time. They passed the other party members who had split up (and couldn't find them).
Good times. Players heads were very fucked with.
They did eventually figure it out.
Many reasons.
Some people are taught gender essentialism from a young age. Women are like this, men are like that, and there's no way to change it. It's just nature (or God) that women clean and take care of the house, and men go out and hunt.
Many boys are socialized from a young age not to cook or clean. Many girls are taught that that's what they do. Have you seen this in your life? A family gathering, where the boys run off to play and the women and girls stick around to clean up? Children learn from what they see and what they're taught.
It's only recently that women had any shot at financial independence. Women weren't guaranteed the right to open a bank account until 1974, in the US. Sexual discrimination is a problem with finding a career to pay one's own way. From that, one can infer that some women "put up with" shitty men, because the alternative is destitution.
Some women may believe that changing it is just too much work- it's not an immutable nor innate property of men that they don't cook or clean or know anything about the children, but changing that would be an overwhelming amount of work. If the man's not interested in changing anything, it's even more daunting, and may damage the relationship.
Also some men get violent if they feel threatened, insulted, or hungry.
These are just some things I've read or women have talked to me about. I'm a dude doing the best I can. Talk to the women in your life (but don't make them teach you a whole seminar for free, heh.)
