They don't dislike taking care the child, so the wife can work with feeling good. Both men and women tend to become independent of each other. This independence has caused high rates of divorce, but in the future, that independence will be successful, because they will respect each other. Rate of divorce will decrease. Contrariwise, in Japan, man only tend to work and hope the woman will be a housewife.

That's why they depend on each other. That is difference of America. If this situation continue, rates of divorce will increase. Finally, I want to know next thing. In the U.S.A, people call their superior, teacher and parents by their first name.
