If my wife is more capable and makes more money than me, without
additional income support from my part to lead a comfortable life,
I would gladly take care of the kids. 
I'm a firm believer of leaving things to another person who is
able to do it a lot better than me. Eg. If I suck at investing,
leave it to the fund manager who would do a better job. If I can't
cook well, why not hire someone who can?
In life we just have to play out the role that we are good in.
Don't have to do everything ourselves and suck at it.
Ohhh...I know some forumers might think, what if I'm lousy in
bed with wifey hahaha...
Eating soft rice?
Actually i think its the ego of men and the asian culture that
women are the reserves rather than the players.
Don't have to worry about the status of women too much, they're
now catching up with man, better worry about ourselves.
However, i still think that men are made in a way that they are
more suitable as front line players while women take the
backstage.
Men are physically stronger, think more logically and are able
to suppress their emotions better.
Women, on the other hand, are not as muscular(i heard it is to
provide comfort for the baby), tend to be more emotional and
caring, thus making them better care givers than employees.
While,all of us are made for a reason
