The article however was about men primary. Which I found interesting, because perspective of male who would prefer different tradeoff is rarely available.
Other times one of them (can be also a women) takes advantage of the situation and the other one does not have much choice subsequently or figures it out only after a while maybe when it is too late. (If women hates her job, it is easier for her to claim that kids need mom longer/more to stay out of workforce longer which puts more pressure and stress on husband. If stereotypical geek claims that it is just not possible not to stay late, he can avoid some of boring housework. )
In other cases, the choice is made by tradition and peer/family pressure which prescribe proper roles (like in case of deeply conservative catholics I know - roles are strict and given by god end of discussion).
So, once there are children involved, it is not unusual for the wife to just suck it up and do what the kids need at personal cost to her. It often makes little sense to try to hold hubby's feet to the fire and insist on him doing his fair share at home or whatever.
This is not man-bashing. I am a woman and former homemaker. I do a lot of even-handed writing that tries to consider both sides of the picture. But this is a reality in many marriages. I do not self-identify as a "feminist" in part because, to me, "feminism" is about women wanting careers and to hell with any other considerations. This ongoing argument about equality of the sexes seems to mostly leave out the critical detail of the welfare of the children.
Unless and until we start talking about what works for the family as a whole, including kids, and society as a whole, including families with legal minors, this entire argument about men vs. women and so-called equality will continue to be sick and twisted and will tend to continue to crap on any parent that actually cares deeply about the welfare of their kids, regardless of gender.
Second-wave feminism lasted from 1960s to 1980s.
Dealing with such women is usually a worse experience for me than dealing with most men. Such women are typically pretty toxic.
In a sense, no one talks about these considerations openly, ever. So it comes out indirectly through attitudes.
Everyone is supposed to be motivated only by positive things, you are supposed to stay because you are caring and loving not because you are sucking it up. That idea insults people. You are supposed to work because you love career, not because you don't want to be the lazy nagging stereotype - which you are pretty sure you would turn into if forced to stay at home.
If you want to call yourself a feminist and talk about getting equal rights for women, then I don't want to hear your crap about how your ideals only actually apply to women like you but still exclude large groups of women.
I think these are just bitter people who felt "It's a man's world and the least worst option for a woman is to not have children."
That's not an idealistic solution. That is not about making the world a better place. That is not about expecting more of the world. That is basically saying "No point in fighting evil. You can't win."
Turning around and shitting on me because you gave up years ago makes you part of the problem, not part of the solution.
