"Why should there even be a "solution"?"
Because we're a progressive world, where we successfully freed women from the oppresion of having a nice household, a partner who takes cares of them, and pursuing the ultimate biological goal of reproduction. Now they can enjoy being forced into being competitive just as men are. Remember girls, now you have to earn the right to use your womb now, better get working because you'll need the money in case you decide to unfreeze your eggs and have a baby a couple of years before your retirement.
So better get into engineering even if you don't like it because babies are fucking expensive now! Uh? you don't like it? well that's because your internalized patriarchy doesn't let you think straight you silly girl.
Obviously the only real solution is to force all children to be taken at birth to be raised and educated in government-run facilities until the age of majority, safe from bad parenting decisions and dangerous political/ideological ideas.
I felt the need for the '/s' sarc tag, as there are actually a number of people, some in positions of power, who would take the above as a given, that children belong to the State first and parents second.
