Goober5000: that's a poor excuse for gender roles and misogyny - and 

 your analysis is incorrect
halving the workforce halves productivity, which is vastly damaging to the economy.  A country were half the workforce cannot work because their female is never going to be economically as strong as a country where both the men and women work.  Furthermore the psychological affects of being treated like a second class citizen (being forced to be submissive, brainwashed to be) are profound and entirely negative.
You knwo the divorce rate is _HIGHER_ ammong fundamentalist homes, and the spousal abuse rate is well over twice as high amoung fundamentalist homes.
However having a parent around is good while the child is very young - that's why germany offers workers "Parents Pay" till the child is a certain age - both MEN and WOMEN are eligible, and only one of the two people in a family can take it - and yes men do take it. 
If you CHOOSE to stay home while they're young, that's good - don't expect it of women just because they're women.  If you think it's so great and your wife wants to work, why don't you be a father and stay home.
