That's because after the Islamic Revolution, Iran's economy declined and many people died in the war. The number of men has decreased, and the number of women is much higher than that of men, which leads to the plan of polygamy in Yilan, thus advocating family planning to increase the number of Iranians and enhance national strength.

Personally, I feel that the development of a country depends on the development of its human population, so the population of a country is very important. Just like an old saying, many people make light work, which fully shows that a country with many people will be strong and will work hard towards its own development and achieve its goal.

At that time, before the failure of the Iranian revolution, their population was very small, the population growth was very slow, and the development with a small population was naturally not ideal. Therefore, after the Iranian revolutionary war, the Iranian war was very disastrous, and there were many deaths in the army. It is precisely because of this war that the number of people in Iran has been very small. At that time, it took Iran very little time to make its population grow rapidly, which is why it is called the fastest growing country in the world.

Western countries themselves are different from northern China. Western ideas are more open, so polygamy is proposed to encourage them to have more children, whether they can afford it or not. Neither of them is against it, but both agree with the system. It is precisely because of this system that Iran's population is growing rapidly and its fertility rate is rising. What Iran needs more is an increase in population.
