Men do housework when it is absolutely necessary. There maybe exceptions where husbands do it regularly and the wife is very lucky.
Just like the society expects men to be the providers, women do the housework as reciprocation. It is a mutual arrangement.
There are gadgets to help and there are servants in India to chip in. Husband has to help his wife whenever the need arises and a husband who thinks it is beneath his dignity is unfit to be called a partner.
And women also go to work to help the family financially.
