To be fair, I know men who absolutely do their fair share around cooking, cleaning, and childrearing. However, obviously, they are not the ones bragging on forums about constantly working overtime nor are much visible in their hobbies etc.

Edit: for those who downvote - there is opportunity cost for doing these things. At minimum, he is more tired when he does that. And it is not possible to do fair share of house work if you work 70 hours a week every week. Nor when you train or work on hobby additional 20 hours a week.

It is not like men who did all those things would have longer days or magically needed less sleep.
