It strikes me that there is some kind of cognitive dissonance that prevents people from recognizing their time as a commodity. I understand and support the push to normalize women in the workplace in leadership positions but there seems to be a failure to recognize the cost.
I think the "traditional" family roles of mother stays home and father works are outdated but I think the train goes off the tracks when people want to throw the whole idea out completely. To me, the outdated part is just the gender roles. I don't think both parents can be CEOs, someone has to be the primary caretaker because, as so many mothers have said in the past, it's a full time job. Couples of any configuration need to have an understanding of who is going to take what responsibilities when they have kids and often/sometimes that's going to require sacrifices in both career and earning potential for one or both parents.
