It's unusual now for father to persue (追求)his trade of other employment at home, and his children rarely, if ever, see him at his place of work. Boys are therefore seldom, trained to follow their father's business, and in many towns they have a fairly wide choice of employment and so do girls. The young wage-earner often earns good money, and soon gains a feeling of economic independence (经济上的独立). In textile areas it bas been customary for mothers to go out to work, but this practice has become so widespread that the working mother is now not an unusual factor in a child’s home life, the number of married women in employment having more than doubled in the last twenty-five years. With mother earning and older children drawing wages, father is seldom the most important figure that he still was at the beginning of the century. When mother works, economic advantages increase, but children lose something of great value if mother’s employment prevents her from being home to greet them when they return from school.
