Hearing that Liu Jin had another high-level argument, Emperor Hongzhi, Liu Jian, Xie Qian, and Li Dongyang hurriedly cheered up, ready to listen to what this Liu Jin could say about the population and land.

"I have always encouraged reclamation in the Ming Dynasty, but the land in the world has always had a limit, and it is impossible to grow endlessly, especially since I estimate that the amount of taxable land in the Ming Dynasty must be less than when the country was founded."

"But the population is constantly growing, especially in the past hundred years, and the population is growing rapidly."

"Let's assume that there are 10 shares of land in the world, and at the beginning, there are 10 people in the population of the world, and each person cultivates a field and pays a tax, so at that time he can receive 10 taxes."

"As the population grows, soon, these 10 people will become 15 people, so 5 people will not have their own land, and among the 10 people who originally owned land, some people have been admitted to the imperial examination, and there is no need to pay grain for farming, so there may be several people who donate their land to this person's name."

"At this time, the field was still 10 shares, but only 7 taxes could be received, and the extra 5 people could only become hired farmers because they did not have their own fields, and they could only farm for those who had land."

"Fortunately, these 10 plots of land are enough to feed 15 people, and although there are times when a few people go hungry in the event of a bad harvest, they are still able to survive on the whole."

This simple analogy mentioned by Liu Jin, if it is a person of later generations, it is estimated that many people have seen it, which is a very good and vivid example used to explain land annexation on the Internet, which can explain the ancient land annexation and dynastic change very clearly.

Emperor Hongzhi, Liu Jian, Xie Qian, and Li Dongyang naturally hadn't heard of it, but now when they heard Liu Jin's words, they suddenly felt very novel, and at the same time, they thought carefully while listening.

"When the population grows to 20 people, the land in the world is still 10 points of land, and at this time, the output of 10 points of land can no longer meet the needs of 20 people, and there are more hungry people."

"And at this time, there will be more people who have the privilege of being exempted from taxes, and at this time, the amount of land donated to the tax-exempt people may reach 4, 5, or even more, and the tax revenue that can be collected may only be 5, or even less."

"Half of the 20 people are hungry, and these hungry people will not really wait to starve to death in vain, they will definitely find a way to grab the land into their own hands, and rob other people's food to fill their own land."

"So the 20 men started fighting, fighting with each other, and in the end there were only 10 people left, and the remaining 10 people redistributed the land, so that everyone could eat again, and they would have their own land, and the story would go on."

Liu Jin was concise and to the point, and soon explained the relationship between population and land.

Only Emperor Hongzhi, Liu Jian and others opened their mouths one by one, they are all smart people, where can they not hear, although this Liu Jin is telling a story, but in fact, it is about the rise and fall of a dynasty.

Regarding the change of dynasties and the cycle of history, they have read too many books, and studied too many and too many histories, but they have never explained the reasons for the changes of dynasties from the perspective of population and land as they do today.

In the past, they always believed that the change of dynasties in the past dynasties must be caused by the corruption of the government, the faintness of the king, the pro-villain Yuanxian ministers, or the barbarian invasion and many other reasons.

But I never thought that because the population was increasing, the land was still so much, and the land was slowly concentrated in the hands of a few people, which led to a sharp contradiction between the population and the land, and eventually led to the change of dynasties.

From this point of view, it is very novel and eye-opening, and it seems that it has seen through the root of the reincarnation fate of thousands of years of Chinese history at once.

"Are we in a period of 15 now?"

Emperor Hongzhi looked at Liu Jin, he understood Liu Jin's words, and also carefully compared, and found that the period of the 15 people mentioned by Daming and Liu Jin is very similar.

"Maybe it's 16 or 17 people."

Liu Jin thought for a while and said, the Hongzhi Dynasty already belonged to the middle of the Ming Dynasty, and in another hundred years, the population will be larger, and the land annexation will be more serious, even if there is no Xiaoice River period, the Ming Dynasty will be like other dynasties in history, accompanied by peasant uprisings, and finally ushered in a change of dynasty.

Li Zicheng was able to break into Beijing City and let Emperor Chongzhen hang himself on the crooked neck tree is enough to show all this, even if he did not conceal his entry into the customs, in the end, the world will definitely not be surnamed Zhu again.

"Let's talk about the household service system formulated by Taizu."

"In the Taizu period, because the world has been in turmoil for a long time, especially the century-old catastrophe of Yuanhu, the world is sparsely populated, and all kinds of waste are waiting to be rebuilt.

"Because this policy was the most suitable policy at that time, it could recover as soon as possible and make the world stable."

"But now it's completely different, the population is increasing, there is still so much land, and there are more and more scholars with fame, more and more people are exempt from taxes, and the land is slowly concentrated in the hands of a few."

"If this population has not moved, everyone is still confined to the same place, they will not have enough food, no clothing, and if there is a natural or man-made disaster, they will not be able to survive."

"At this time, once people can't live, the consequence will naturally be that people are displaced everywhere, and beacons are everywhere."

Liu Jin looked at Emperor Hongzhi's face, it was obvious that Emperor Hongzhi's face was not very good-looking at this time, but Liu Jin did not stop and continued.

"So in this day and age, if we want to break this situation, we can either reduce the population or increase the land."

"When the dynasties changed dynasties, it was actually a process of population reduction, and war was the most effective way to reduce the population."

"But now, it's obviously not possible, so we have to move the surplus population of the world to other places, and the world outside the Ming Dynasty is very vast."

"This Golden Continent is dozens of times the size of the Ming Dynasty, the land is extremely fertile, enough to feed dozens of times the population of my Ming Dynasty, and this Nanyang region, the land is fertile, and the rice grows three times a year, which can also feed a large number of people."

"This Australia, Africa, Tianzhu, etc., as well as the vast area north of my Daming, how vast the land outside the Daming Dynasty is, enough for us to expand for countless years."

"As the saying goes, people move to live, trees move to die, in fact, this is the truth, our Chinese ancestors also followed this truth, so from the Hanzhong region has been slowly expanding to the current vast territory, so it can feed the current tens of millions of people."

"If it had been confined to the Hanzhong region, it would have been impossible to have such a large population and such a vast land!"
