Because they are culturally indoctrinated to believe that their handsome prince will make their fragile princess lives complete before they can read.
Yes social conditioning is a thing, yet biological conditioning is also a thing. It would be unreasonable to suggest it is only one of these things.
It makes perfect evolutionary sense why a woman would naturally be attracted to prince charming without social conditioning. A woman wants somebody that has the social / physical power to protect her whilst she is raising kids, the person that raises the highest is more desirable because this indicates he has better genes.
Because boys are culturally indoctrinated to believe their value as male is linked to their ability to kick and throw a ball before they are out of nappies.
It also makes sense why biologically this would be the case. This is why babies with highher T look at objects more instead of faces. The boys will be the ones that hunt and fight when they grow up. It makes sense for them to enjoy sports (which are kind of simulated combat) more. If evolutionairly speaking women where just as eagar as men for this, then when an army appears, they would be more likely to get up and fight it instead of staying back. This would mean more women die in the battle. If the other army has just men, then there women are saved. Next generation when they fight again, the army with women fighters would be much smaller as they have been unable to repopulate as fast.
Societal culture influences life choices and ours is a patriarchal society.
I worked in early years education in the 90s and it was as clear as day that adults encourage traditional gender roles and behaviours in their children from the moment they are born.
Gender roles doesn't necessarily mean it's patrirchal. If you go back 200 years then yes it was very difficult for a women to rise to any position of power, this is of course unfair and sexist. Yet the flip side is, men died far more and earlier, men were half as likely to pass on their genes, etc.
I think there is a tendancy to look at the top 20% of men who are merchants, kings, politicians and just assume that men had it great. When in reality the other ~80% also had a real shit time, working in factories 12hrs a day with no sun light, doing dangerous jobs like mining or fishing, and being forced to fight wars. If this was truely pariarchal, then why didn't they force their women to do these jobs?
I'm not saying women or men have it worse. Just that the argument is more nuanced than saying any inequality between the gender is due to social conditiong / patriarchy.
