There are many answers to this. But ultimately modern society masculinizes women and teaches that the path to success is by competing against men and acquiring, what were traditionally defined as, masculine characteristics: being dominant, going after what you want, being competitive, aggressive etc.. Notice how it is celebrated when a woman breaks into a traditionally masculine arena. The coming soccer worldcup in Qatar will have the first female referee. This utterly unimportant fact is seen as a victory for women. Now little girls can have dreams of refereeing male sports. I mean, it's bizarre when you think about it. Meanwhile motherhood, sensitivity, mercy and other traditonally feminine values are devalued and shamed. Nowadays even the concept of shame is shamed
"Oh, she's just a stay-at-home mom, must be lazy. Why does she need to serve
a man at home, when she could be serving her bosses for a paycheck instead? Children? Nah we off that".
We value women more as taxpaying citizens than mothers. Who benefits from this? Not families. Not children, and ultimately both men and women end up suffering in the long run. The ideal of interdependence and harmony is more or less dead in this modern hyperindividualistic society.
We're all competing in the same arena basically and that includes the sexual arena, hence women want to become as sexually "liberated" as some men have been traditionally.
Ironically, this type of thinking is a time-bomb under the very society that promotes it. We already see falling birthrates in all industrialized nations, most of them below replacement rate. Reproduction is the most basic animal function and we seem to be failing miserably.
Not to say that women didn't have legitimate grievances in male dominated societies. They did, and still do tbh. But the feminist cause was hijacked long ago by governments who need tax revenue and marketing companies who want to sell products.
