Women’s roles have changed throughout the world in recent years, but nowhere so obviously as in America .As the roles of women have changed ,so have men’s .In many American homes today ,the husband still carries on his traditional role of breadwinner ,while his homemaker wife is in charge of the home and child—raising.
