In many homes, divorce is caused by the “battle between the sexes.” To understand the problem, one must remember that the modern American woman is freed. During childhood and adolescence(青少年期), the American girl is given freedom and education which is equal to a boy's. After completing school, she is able to get a job and support herself. She doesn't have to marry for financial security. She considers herself an independent, self-sufficient person. She wants a husband whom she can respect, but she doesn't want to be dominated(控制) by him. She wants a democratic household in which she has a voice in making decisions. When a husband and wife are able to share decisionmaking, their marriage is probably closer, stronger, and more satisfying. Otherwise, the couple is likely to wind up in the divorce court.

When a couple gets divorced, the court usually requires the man to pay his former wife a monthly sum of money. If the couple has children, they usually remain with the mother, and the father is expected to pay for their support.

Although divorce is quite common in the United States, 80 percent of those who get divorced remarry. The remarriages allow thousands of people, especially children, to enjoy family life again, but at the same time many troubles have arisen. A well-known American joke tells of a wife calling to her second husband, “Quick, John! Come here and help me! Your children are beating up our chidlren!”

孔子曰：“奢则不孙，俭则固；与其不孙也，宁固。”又云：“如有周公之才之美，使骄且吝，其余不足观也已。”然则可俭而不可吝已。俭者，省约为礼之谓也；吝者，穷急不恤之谓也。今有施则奢，俭则吝；如能施而不奢，俭而不吝，可已。

生民之本，要当稼穑而食，桑麻以衣。蔬果之畜，园场之所产；鸡豚之善，埘圈之所生。爰及栋宇器械，樵苏脂烛，莫非种殖之物也。至能守其业者，闭门而为生之具以足，但家无盐井耳。今北土风俗，率能躬俭节用，以赡衣食；江南奢侈，多不逮焉。

世间名士，但务宽仁；至于饮食饷馈，僮仆减损；施惠然诺，妻子节量，狎侮宾客，侵耗乡党：此亦为家之巨蠹矣。

裴子野有疏亲故属饥寒不能自济者，皆收养之；家素清贫，时逢水旱，二石米为薄粥，仅得遍焉，躬自同之，常无厌色。邺下有一领军，贪积已甚，家童八百，誓满一千；朝夕每人肴膳，以十五钱为率，遇有客旅，更无以兼。后坐事伏法，籍其家产，麻鞋一屋，弊衣数库，其余财宝，不可胜言。南阳有人，为生奥博，性殊俭吝，冬至后女婿谒之，乃设一铜瓯酒，数脔獐肉；婿恨其单率，一举尽之。主人愕然，俯仰命益，如此者再；退而责其女曰：“某郎好酒，故汝常贫。”及其死后，诸子争财，兄遂杀弟。
