Yeah, I totally agree, I just wanted to point out that there is a large part of males that probably wouldn't mind to take up that role in a situation where it would be financially better. I believe this requires a certain cohesion and trust in each other and a specific dynamic as a couple, but I would expect all of that to be there anyway when you decide to have a kid.
The last part was more of a joke than a serious comment. In my close friend group we have a sort of friendly boys vs girls thing going on. Most of us are couples and it is more banter.
Although I am pretty damn confident that I have perfected the art of cleaning when it comes to efficiency.
