“When a destitute mother starts earning an income, her dreams of success invariably center around her children. A woman's second priority is the household. She wants to buy utensils, build a stronger roof, or find a bed for herself and her family. A man has an entirely different set of priorities. When a destitute father earns extra income, he focuses more attention on himself. Thus money entering a household through a woman brings more benefits to the family as a whole.”
