为什么接受太多教育不一定是一件好事

看到Economics Explained出了一个解释学历贬值的的视频，很有趣，就作了下小结。

劳动价值理论是一个经典的经济学原理，它阐述了劳动力和产出价值的关系。人们认为商品和服务的价值是由生产者付出的劳动赋予的，其价值随着人力投入增加水涨船高。组装一台笔记本电脑可能需要的时间和劳力少于打理花园，但是生产笔记本电脑的元件，从开采原材料到精细加工，所花的时间和劳力就比园艺多得多。劳力的价值是另一个影响产出价值的决定因素。许多经济学家不认同这个理论，认为它无法在资本主义社会里实现。他们普遍认为，资本主义社会靠商品和服务创造的价值来衡量它们本身的价值，未来价值的预期、商品的特殊性、实用性都会影响商品和服务的价值。有人用主观价值论来解释被衡量价格的变动，打个比方说，一瓶水对一个脱水的人的价值远超一块钻石。在许多发达经济体，人们目前面临的境况印证了这个理论。高学历群体带来的边际收益正在下降，如果将培养一个高级人才和高级技工所需的时间和资源，投入到培养低技能工作的人力上，后者所产出的价值可能还高于前者。我们处于一个全球经济没落的时代，发达国家正在将供应链转移回国，他们的劳动力市场需要更多的低阶劳力，高学历群体不再像以前一样受欢迎。

看完视频，我的结论是现在的人在求学之前，要对求学的经济投入和回报作深思熟虑，这个学位在劳动市场上是否如以前一样值钱，亦或者这个学位对学生带来的收益有哪些，将所有的因素都考量清楚再作决定，不然选错道路将会耗费更多的时间和精力才能弥补回来。

The labor theory of value is a classic economic theory that illustrates the relationship between labor and the market value of output. People believe that the value of a good or service is granted by the amount of labor takes to produce it. Producing a laptop may take less labor and time than gardening. But the capital that builds a laptop may require much more labor and time than gardening, which only needs few labor and simple tools. The value of labor is another crucial factor in determining the products' value. Many economists don't accept the labor theory, because of its primativeness. The capital societies value goods and services based on the profit taken by the owners of the capital and land required to make it. The expectation of future value, prestige, utility sometimes affect the value of a product more than the production factors that take to make it. The fluctuation of prices involves the subjective theory of value that a bottle of water may worth more than a dimond because of its significance to a dehydrated person. This theory can be applied to the situation in many advanced economies. The added value brought by highly-educated people and skilled wrokers are declining. The resources and time put into tertiary education may not produce as much value as working in low-skill jobs do. As the global economy ends and the supply chains are moved back to their home countries, there will be a hollow in the supply of low-skilled worker in the labor market. Well-educated people is not as popular as before.
