Here's the progression. Feminism won; you can have it all; of course you want children; mothers are better at raising children than fathers; of course your children come first; of course you come last; today's children need constant attention, cultivation, and adoration, or they'll become failures and hate you forever; you don't want to fail at that; it's easier for mothers to abandon their work and their dreams than for fathers; you don't want it all anymore (which is good because you can't have it all); who cares about equality, you're too tired; and whoops--here we are in 1954.
