Why are developed countries not open to accept immigrants?

First of all, the quality of a country's population depends on its actual situation. For some countries, it is very beneficial that the total population is larger than the current total population or remains unchanged. For example, the United States, Europe, Japan and Russia are all encouraging their citizens to have a large number of children. For other countries, population decline may be very beneficial. Such as Kuwait, Iraq and Saudi Arabia. Reducing a person's population can increase per capita oil exports and per capita oil income, and perhaps the remaining nationals will become richer. This is my understanding, and these countries may not think so, because countries such as Kuwait have no propaganda or policies to restrict the birth of their nationals. The population of some countries will also increase or decrease appropriately, which has little effect on their per capita income.

The United States, Russia, Japan and Europe are actually attracting immigrants, but they have not completely eliminated them. How can it be said that it is the opposite policy? If it is the opposite policy, the governments of these countries should organize or encourage their nationals to emigrate. Such behavior is the opposite policy. China believed that the smaller the population, the better. China should be a country that encourages immigrants. In fact, China has not done so. It is really puzzling that it only reduces the Han population in China through the birth restriction policy. )

In fact, the United States is now the largest immigrant country in the world. The United States itself is an immigrant country. Europe is also an immigrant area now, and it absorbs a large number of immigrants every year. Russia has also absorbed many immigrants from CIS countries. The Japanese also absorbed a large number of immigrants from China and the Korean Peninsula. The current situation is just that the migration is not so convenient and there are policy restrictions. For example, the United States has raised the immigration threshold, but it has not closed the door to immigration.

National policies need to be considered in many aspects, not only the economy, but also other factors. If a policy is correct only from an economic point of view, it will certainly be implemented. Russian immigration law is representative. China people living in Russia are deliberately excluded from absorbing immigrants in Russia. China's work in Russia has become an integral part of local economic activities, and even an important part in some places. It is very helpful to improve and facilitate the life of Russian residents. However, China people living in Russia are forcibly excluded from the ranks of foreign immigrants that Russia needs to absorb through immigration laws. Why is this? The reason is that Russia not only considers immigration economically, but also considers other contents. Russia has plundered a lot of land in China, and Russia is very concerned about China people. China is found all over the world, but China is not allowed in Russia. The immigration policies of other countries are also considered comprehensively. If they have no economic interests, they will open their doors.

If it is beneficial from the economic point of view, it is beneficial from other aspects, and the country will not open wide, so filtering is essential. If we can absorb high-quality immigrants, why should we absorb relatively low-quality immigrants? If you can absorb immigrants who have relations or relatives with your own country, why should you absorb people who have no relations with your own country? Just from these two points, not everyone can facilitate immigration, but they need to accept the filtering procedure, which is what netizens think, why not let go of immigration.

Economically, a country's ability to accept immigrants per unit time is limited. This factor causes these countries to absorb immigrants and will not be completely open.

There is no advantage in accepting immigrants. These countries can completely eliminate immigrants, but they have not done so, which shows that it is beneficial for these countries to accept immigrants appropriately. The benefits may be economic or political. Malaysia accepted a large number of Malays from Indonesia in order to increase the Malay population in Malaysia, accounting for the proportion of the Malaysian population, so that Malaysia's political power is firmly in the hands of the Malay population. Immigration may also be accepted to safeguard the interests of one's own nationals and to accept their spouses, children or parents abroad.
