How is order established in "Snowpiercer"

First of all, I saw that some knowledgeable friends discussed revolution in long paragraphs. Well, let’s talk about the causes and basis of revolution. The causes of revolution are generally thought to be caused by inequality. According to what I wrote above, politics is about investing limited resources into endless human affairs. This means that inequality is destined to always exist; but if we only take this literally, we will all be dead. All have gone to revolution. Of course not, people have subjective initiative, otherwise what is the use of studying politics. Since it is distribution, it involves the issue of how to distribute. This needs to be analyzed and considered in a specific environment, with a variety of main variables. Without going into details, we will directly give the results. Qualified politicians should stabilize society through reasonable distribution. After giving a definition, let’s go back to the movie and talk about the passengers in the tail car. First of all, strictly speaking, these passengers cannot be regarded as passengers in the strict sense. We can understand them as holding green cards or residence permits, but have not obtained citizenship. Passengers who are not eligible and cannot enjoy civil rights (and they are still the kind left behind by smuggling). It is not mentioned many times in the movie, but it is mentioned repeatedly in the dialogues that the passengers in the tail car were not originally planned by Wilford to be in the train, and they were allowed on the train out of sympathy and pity (although this is not entirely true) This is the case (explained later); this is a major premise, just like every new immigrant to a new country will always be more or less discriminated against, because of their differences and the changes to the current status of the original passengers, At least according to the original passengers. This establishes the irreconcilable conflict between passengers in the tail car and passengers in other carriages. First of all, resources are limited, which means that passengers in the tail car will never enjoy high-quality resource allocation and are destined to be permanently poor. Secondly, the passengers in the front car have to spend resources to manage the passengers in the rear car and provide the passengers in the rear car with resources to maintain basic survival. At this point, it can be reflected from the conversation between Curtis and Nangong in front of Wilford. : In the first month they were allowed to enter the tail car, there was no inflow of resources; then Wilford spent more than a month creating recycled sustainable protein made by cockroaches for them to maintain their necessary life. At this point, we may even regard Wilford as a saint, because Wilford not only provided them with trains, but also food and water. But is this really the case? No, Wilford also gained profits from the passengers in the tail car, including the violinist who played for the passengers in other cars, and the children who kept the perpetual motion machine working. The profit he gained from the tail car in the past 18 years is not explained in detail in the movie, but it is enough to illustrate that Wilford He is not a saint, nor is he letting the person in the back of the car get on the bus simply out of sympathy and pity (selfishness is the original sin of mankind).
