That part I understand but why do all of the dedicate themselves to arts and fashion instead of ...
I have a mansplaining theory, which might be severely biologistic and sexist too... But since this here is the Internet, the virtual try out zone... and perhaps it goes a bit OT and the moderators save me.
So: For the longest time human beings were hunters and gatherers. What means probably rather that the males were more of the hunters and the females were more the gatherers...
The abilities to hunt can easily been measured: tracking - how good; spear throwing - how far, precise; running - how fast, how enduring.
But gathering, that is more of a group thing! If one gatherer or better gatheress spots the berries, all harvest berries; same for mushrooms and so on... it is difficult to measure here.
But women have the "will to power" (Nietzsche) too! So, how can they show, that they are "valuable"? More than the others?
How are things gathered? They are put in a kind of archaic handbag. It was either decoratively selfmade, or out of materials the mighty hunter-husband brought home.
And until today many girls define themselves this way: either about the ability to decoratively improve things or
Woman A: Oh, what a fine handbag, is this crocodile?
Woman B: Yes, my loving husband brought it home. He hunted it down with his bonus cheque from Goldman Sachs!
And this is, to make a long story short, why young women prefer the decorative arts and fashion and older women luxury.
?
So, if the Princess Alexandra here is doing some fashion, she is trying alpha girl stuff and is showing her value-ability.
Now, please, don't stone me! It is just a theory!
Please!
