Who should be responsible for household chores?

From time immemorial, it is generally believe that the bulk of the housework lies on the woman of the house, whether she is strong enough to do so, or in the right frame of mind to do it is not of utmost importance, the bottom line is it’s an obligation she must fulfil. I was privy to an argument between two of my office colleagues where one of the two guys bluntly stated that he married his wife to take care of his home and raise his children, which is the only work he believed a woman should do and not running helter skelter to meet up with office deadlines and so on. Then I asked him what he does in the house to assist the woman, and he simply replied that he washes their cars in the mornings and that is all. So in essence, the woman cooks, do the dirty laundry and ironing, prepare the children for school, drive them to school, drive back home to take care of the mess left behind, prepare lunch for the children, do afternoon school runs, help the kids with their homework, shopping, all for the man to come back from work with his own demands. My next question to the egoistical bagel was when does she usually wake up and sleep, he said she wake by 4am and sleep 11:30/12pm which he said is not bad because she has all day to catch up on her sleep and rest. From what I’ve heard so far and the appearance of the woman from the few times I’ve met with her I thought to myself that it was no wonder the woman always looked exhausted no matter the time of the day. She does not have any spare time for rest, she is always on her toes and the husband does not seem to mind. He looks robust and well fed, because he does absolutely nothing, I’ve heard him several times arranged to have his car washed by the parking lot attendants.
The other guy is a bachelor and he felt that was an abnormal way to treat a woman whom you professed to love and cherish, I agreed with him because the guy turned his wife into a slave in her own house.
I don’t think it is right for a man to leave all the housework for the woman alone coupled with her responsibility as a wife and mother. If the husband cannot assist directly due to a reason or the other, and the children are not old enough to also lend a helping hand, then he should employ a maid for her; take up the gender roles in the household duties to reduce the work overload on the woman.
Men should remember that how they use/treat their wives has a direct effect on the looks/appearance and health of the woman. Even though the husband is the head of the family, he should be ready to relieve the woman of some of her duties once in a while and also be willing to share the household duties equally with the woman and also adapt his lifestyle to being married just as the woman did.
