理论都很高深吗?是,但又不是。比如,据一位学者统计,欧洲一些国家犯罪率下降是因为出台了允许堕胎的法律。这一法律让那些在不幸家庭中出生、容易犯罪的孩子没有生出来。现代社会的离婚率为什么比过去高?都是感情问题?不尽然。经济学家弗里德曼给出了另一个说法。现在许多丈夫想吃点好的、穿得漂亮,不需要一个能干的妻子,他可以随时上街去买。而妻子想一件漂亮的家具,她也不需要一个懂木工的丈夫,家具城里多的是。而在过去,娶一个厨师的女儿,嫁给一位木匠或屠户,在乡村地区都是划得来的事,双方都想在未来的生活中花费小些。 Is the theory so profound? Yes, but not. For example, according to one scholar, the decline in crime rates in some European countries is due to the introduction of laws that allow abortion. This law has given birth to children who were born in the unfortunate family and were prone to crime. Why the divorce rate in modern society is higher than in the past? Are the feelings of the problem? Economist Friedman gives another explanation. Nowadays, many husbands want to eat well and wear well, they do not need a capable wife, and he can go shopping at any time. The wife wanted a beautiful furniture, she does not need a husband know woodworker, furniture, the city is more. In the past, marrying a chef’s daughter and marrying a carpenter or butcher was a draw in the countryside, and both wanted to spend less in future life.
