Well, in my opinion, it's a little inefficient and unjust if the wife is doing all the work. If the husband sits back and does nothing, well, that IS being lazy; and laziness is a poor attitude.
The problem is not women's liberation, since, of course, women are people who are as important as men.
The problem is that after a full-time shift at the office, people do not come home with the reserves of energy needed to also do even half of the housework required to properly take care of a home with children.
It used to be that a man with a steady job made enough money that his wife was at home with the children, and so him doing his job and throwing everything of himself into it to maintain his position and advance his career, while she did the housework, was a fair and equitable division of labor.
If, on the other hand, the lady of the house also had a college education and a career - her husband's position would be such that between the two of them, they could afford a maid. A maid who was not an illegal alien, either.
So, in the immortal words of a well-known American saxophonist, "It's the economy, stupid".
