What is the impact of immigration on developed and developing countries respectively?

The oldest migration of mankind is also immigration, which has promoted the progress and development of the whole mankind.

During the Han Dynasty and Emperor Wudi of the Han Dynasty, the Xiongnu in the north moved westward in Central Asia for 300 years. After that, a new nation appeared, which caused turmoil in Europe, which not only promoted ethnic exchanges between Europe and Asia, but also promoted cultural exchanges!

Genghis Khan, a Mongolian, and his descendants have a far-reaching influence on many countries in Europe and Asia.

The establishment of the United States, European colonial rule in the world, African blacks being sold to the United States, and China workers are immigrants.

All these forms of immigration are a kind of promotion, including culture, economy, science, race and religious belief.

In the new century, Canada, the United States, Australia and New Zealand are the mainstream immigrants. These immigrant countries have many preferential social policies and the world's first system, medical care, education and so on! And democracy, freedom and legal equality that the people most pursue! These are places to attract new immigrants!

Of course, if you want to immigrate now, there is an eternal truth in any project, that is, you can bring what you want to the immigrant country, and your colleagues can't bring anything bad to the immigrant country, whether it's investment or work. You can't go abroad if you have infectious diseases! Therefore, the most profound influence on developing countries and developed countries should be the flow of talents, and of course there are many, many influences!

Give a satisfaction, dear! Hmm. How interesting
