Man Kun: Why do economists welcome immigrants more?

There are three main reasons for this.

First of all, many economists, especially conservative economists, have liberal tendencies. Since Adam Smith (Adam

Smith) taught us the beauty of the free market and the magic of the invisible hand. We don't want to ban mutually beneficial transactions between adults. For example, an American farmer wants to hire a worker to pick fruits and vegetables, even if the worker happens to be born in Mexico, this does not seem to be a convincing reason to stop the deal.

Secondly, many economists, especially those liberals, have an egalitarian tendency. They believe in the philosopher john rawls.

Rawls' theory of justice holds that special consideration should be given to the influence of policies on the poorest. When considering immigration, there is no doubt that those who are in the worst situation and those who are closely related to the policy results are poor workers who are eager to come to the United States to earn a better life for themselves and their families.

Third, economists from all walks of life admit that our own profession has benefited a lot from the influx of foreign talents. In the past few weeks, the economics department of Harvard University, where I am the director, has recruited six candidates for the positions of two assistant professors. Of these six people, three are Americans, one is German, one is Argentine and the other is New Zealand. These two jobs will be offered to two teachers and scholars who are considered to be the most capable, regardless of nationality.
