(1) Education transforms the possible labor force into the realistic labor force; (2) Modern education is an important way to produce science and technology and promote economic development; (3) Education is an important factor to improve the quality and productivity of workers; (4) Education can produce economic benefits and is a new growth point of economic development. That is to say, we go out to study, find a satisfactory job, earn a considerable income, and then live as we want, so that education will not fail, and then some of us with strong abilities will engage in research work related to science and technology, and their creativity will promote the development of science and technology and even social progress and change. We will get different social productivity because of different education levels and abilities, so we will get more or less wages, to a certain extent. This is our human capital theory. In other words, most people with high incomes don't have too low academic qualifications.

Therefore, the economy determines education, and education reacts on the economy.
