What happens to a marriage when the wife unties the apron strings, goes out to work and then earns more than her husband? How does a man feel when his wife who has always washed his socks, fed his children and shared his bed suddenly becomes a tycoon? What happens to the children when Dad becomes the housewife? What do they tell their friends? In the first of two programmes, Jeanne La Chard talks to families where Dad stays at home and families where the wife is the major breadwinner.
