I feel that it helps the entire family appreciate what they all have. Both share everything. If the wife stays at home and the husband goes out to work, the wife should be responsible for undertaking the household chores. The best example to be followed is of our beloved prophet. If anybody gives me a proof that this is a woman's job, I'll vote that men don't have to do them.
Mercy is above everything.
Please study Islam well. If both spouses work, that means they 've to share all life issues. It's not only the wives who live in the house and get things messy. If the wife works, he could help out by taking care of the kids on weekends, to give her some time to herself. Cultural bias, I guess.
