My brainwaves were captured by 63962453287387629, and she smiled at me and said, "My dear, your idea is the result of the gradual development of our planet. What I'm talking about is how the people here move from the age of inintelligence to the age of the mentally handicapped, from the age of the mentally handicapped to the age of shallow intelligence, from the age of shallow wisdom to the age of deep intelligence, from the age of deep knowledge to the age of general intelligence, and finally from the era of knowledge to the era of universal wisdom. During this period, the state began to take shape, marking that the governance ability of society had begun to transform into a society governed by man, and people's intelligence began to move from weak to shallow intelligence. After the formation of the Dali reclaim, people's lives gradually stabilized, and the stability of the environment also provided conditions for population growth, and soon the number of people reclaimed in Dali doubled in a few decades. Production has also developed rapidly, and although the producers at the bottom are exploited layer by layer, it is much better than the environment for survival in the dead. Some industrious people gradually lived a life of food and clothing, and the products they produced were surplus in addition to their own use. In the beginning, the nearest grain was exchanged for some vegetables, and the agricultural products produced in the land were exchanged for some game, production tools, and clothing and other daily necessities. At that time, the form of exchange was barter, that is, exchanging a certain amount of grain for a certain item, and the transaction was made when both parties agreed, and there was no certain standard. For example, some people have no rice to eat at home, so they exchange a lot of things for food, so that some rich people exchange their surplus food for things of high value. After a long time, when they saw that it was profitable, they became professional merchants, specializing in speculation, and when there was more food, they exchanged other things in their hands for more food, and when there was less food, they threw out food in exchange for more goods, and gradually became richer, and even exchanged for land. Some people who live in embarrassment exchange their land and even their children for a living, and the rich people are used as slaves after exchange, and they do not work themselves, and they become silverfish who do not work for nothing. The affluent life of silverfish has aroused the envy of many people, and it is also the direction of everyone's efforts. Most people are driven by the wealthy people, work hard to produce, and also want to enter the ranks of the rich. Such an exemplary role is more useful than the chief's persuasion of farming, and greatly promotes the development of production. During this period, in order to improve production capacity, people also changed the mode of production, basically abandoned wood, stone, pottery tools for excavation, ploughing, loosening, harvesting, hunting, and began to use silver, copper, tin, lead-based metal tools with low melting points, although these tools are not wear-resistant, but they are sharper and more convenient to produce. At the same time, they also began to use animal power such as cattle and horses for agricultural production, which could reclaim large areas of land, which promoted the development of agricultural production, and most people could make ends meet, and they could also have a small surplus. In turn, exchange was promoted, and some professional merchants moved from nearby transactions to long-distance transactions, and this team continued to expand, and derived transportation, security, liaison and other industries, and the whole country of the Great Reclamation can be seen everywhere from afar trading teams. At the same time, the smooth flow of logistics has also spread the advanced production methods in various places, learning from each other, and presenting a scene of post-catastrophe prosperity. At this time, some wealthy people, who were accumulating more and more wealth and becoming more and more powerful, raised a large number of domestic slaves and held weapons. At their instigation, in addition to extortion and forcible seizures, they also bullied men and women, robbed homes and houses, did whatever they wanted, and did many evils. Those at the lowest level, especially those who were sold into slavery, were ruthlessly driven to work hard every day due to the exploitation of the chiefs at all levels and the bullying of the silverfish. Not to mention being deprived of all the fruits of their labor, they will also be treated inhumanely, and they will also live a life of being unclothed, hungry, sick and untreated, unable to help themselves, married and married, and neither human nor animal. I found in the literature that there is an article about the laborers at the bottom cursing silverfish, which roughly means: I am engaged in heavy labor, I dare not slack off under the whip and stick, I am tired and tired every day, and I have no freedom of movement. The fruits of my labor have been taken away from them all, and nothing has been left for me. My woman was also taken away from them, and we love each other but cannot stay together. Why are they? It's not that I have been exchanging my sweat for wealth, and I am cursed to use it to crush me. All this tells us that commodity exchange is the initiator of the inequality between the rich and the poor, and it also has a strong smell of blood and sweat. However, it can also promote social development and bring impetus to the expansion of production. There are pros and cons to everything. ”
