Can immigration benefit both sending and receiving countries? Under what circumstances can I do it?

For exporting countries, the disadvantage of immigration is mainly brain drain. But this is basically a necessary stage. Whether it is Japan, South Korea and Taiwan Province, or China and India, which are almost at the same stage now, a large number of talents flow to developed countries during the take-off stage; With the local development, this trend will gradually weaken. From the changing trend of the number of returned overseas talents in China in recent years, it can be seen that the situation is not as terrible as some alarmists say. The advantage is to increase exchanges and bring back the experience and technology of developed countries. Although the proportion of brain drain is not ideal, the specific figures should not be underestimated. There are still many immigrants who have obtained foreign nationality, and they are still engaged in various activities in China, mostly in the economic field, and the benefits are also foreseeable for the sending countries. Moreover, a large number of immigrants will gradually change the views and concepts of receiving countries on immigrant countries, which is beneficial. Another advantage is to release political pressure. Due to the special political situation, many immigrants go out with the mentality of abandoning the motherland, which actually relieves the pressure on the authorities. Otherwise, staying at home is not good for personal development, and letting them complain, toss and stress at home is also a turbulent factor for the authorities' politics. Releasing them abroad can effectively avoid domestic political disputes. According to the current government's plan, when economic development and social maturity fail to meet expectations, political reform is basically much cry and little rain, which is the difficulty of "transition period" in official discourse. As an ordinary person, there is no need to accompany China through the transition period. It is human nature to go out for development based on personal destiny, and it is also a normal phenomenon in the macro history of China. As for saying that the rest are poor, it's just a joke. The truth is far from what the cynics who complain about everything see. From a macro perspective, the development of China is irresistible in history, and endogenous factors will gradually become the driving force for change and development. Within a hundred years, the change of this land will definitely be the most commendable course on earth.
