The 'New Man' theory - where the husband does his fair share of household chores - is a myth. As any working woman will tell you, women are now both housewives and hotshot yuppies but men haven't gone from being breadwinners to housekeepers.
A University of Michigan study has shown that the number of hours wives spend on chores has fallen from 19.5 a week to 14.5, but that's because of technology - vacuum cleaners and dishwashers.
Husbands, on the other hand, do an average of seven hours a week of housework.
Some 26 per cent of wives now earn more than husbands - up from 15 per cent in 1980. Those earning 50 per cent more have doubled to nine per cent.
"There is something about the experience of being a wife, as opposed to a husband, that causes even high-earning wives to spend considerably more time on housework than their husbands," The Daily Mail quoted researchers Alexandra Killewald and Margaret Gough as saying.
