Each and every one of us has never had an option not to have a Big Career. At a minimum, we've always had to fend for ourselves financially, and even in solid long term relationships/marriages with successful men, our income is both needed and expected.
Meanwhile, the caregiving / household maintenance expectations placed on your average Western woman haven't changed, she just has to do them on top of her day job now.
There's a lot of lecturing from "trad" guys online who think everyone should have stay at home wives and lots of kids, but even women who want this type of partnership often can't find men who are willing and able to actually financially support such an arrangement. Every woman I know has spent her whole 20s and 30s seeking wholesome, long term relationships with men who want marriage and kids, at least in an equal and respectful two income home, but they are pretty hard to find. If we can't find a guy in time or we get unlucky (bad breakup/divorce), we're blamed for being "too career oriented" to procreate. No one asks why so few men are serious about marrying us, though. I don't know any women who actually chose their career over having kids, but I do know plenty who figured, 'well, if I have to fend for myself while I look for a guy, I may as well do my best to take care of myself financially.'
I know it's hard for men too. But I don't think men realize the heavy implications that the latest waves of feminism have had in terms of what's expected of the modern young woman. And something has broken between the sexes that seems to make it harder than ever to form stable, loving families.
