Why is there always unemployment in society? It is unrealistic and unwise to analyze the suggestion that the government should set the unemployment rate at zero.

Because unemployment is divided into involuntary unemployment and voluntary unemployment, involuntary unemployment means that people who have the will to work and the ability to work cannot get employment opportunities, and the government can adjust involuntary unemployment. Voluntary unemployment refers to people who have the ability to work but are unwilling to work. Many college students have the ability to work, but they voluntarily lose their jobs because of wages and other reasons. Therefore, it is unrealistic for the government to reduce the unemployment rate to zero. Why is it unwise to say so? Because even if the unemployment rate can be turned into zero, it is unwise, because although the unemployment rate is high, it is not good without unemployment, because the unemployment rate can be used as a wake-up call to warn those who have jobs but don't work hard that they will lose their jobs. It is unwise to zero the unemployment rate.
