It should be said that education and high income are not completely equivalent, but they are highly related. Because in the process of receiving education, it is actually the process of improving individual employability, especially higher education. Because of receiving professional education, in a sense, individuals have improved their employability in the process of receiving education, and strong employability means corresponding high income. Therefore, the two are positively related, but not completely equivalent.

First of all, education plays a leading role in the development of individual employment quality and employability.

Personal employability refers to the ability of individuals to engage in social professional labor. Personal employability is not only manifested in the knowledge and skills of employees, but also in the intelligence and ability of employees.

Second, education is an important way for individuals to increase their employment income.

Different industries, the same industry, different levels, income, social status differences and so on. Individuals always have different professional jobs, which is different from employment income, and it is not only the original ability, family background and other personal characteristics that affect individual employment income, but also social history, social system factors, as well as social and economic development status and level. But since the theory of human capital came out, education has become the most obvious example of human capital investment.
