But then you have to zoom out a little bit and ask why you see so few men become stay at home fathers or househusbands compared to women and is the explanation a problem? Why don't men feel like they can be homemakers or take on the primary caregiver role for their kids? Why do so many women take on those roles? If the answer is really always voluntary preference then maybe it's not an issue but that's unfortunately not the case and the pressure and judgement imparted by society for people to conform to their "roles" creates this dynamic and is bad for everyone.
This set of characteristics has evolved over millions of years, beginning before humans had even branched off the evolutionary tree.

It would be tough to argue that the monkeys’ parents bought them sex-typed toys or that simian society encourages its male offspring to play more with trucks.
