"Even the perfect mathematical society is prone to financial inequality." Why, under equal terms for all market participants and fair exchange of the poor means, is still more than the rich?

The Publishing House of the Myth publishes a book by the candidate of physical and mathematical sciences Sergei Samoilenko, “Probability and troubles. Mathematics of everyday life. " It sets out and accessiblely the widely known “Merphy Laws” (they are “Laws of meanness”). It is recommended to a reader who wants to develop mathematical thinking skills in order to learn how to score informational noise and garbage in the news stream. With the kind permission of the publisher, we publish an excerpt from the 9th chapter of the “thermodynamics of class inequality”.

Among economists, the real world is often considered a special case.

Hongren observation

The modern economy is a large, serious, but peculiar science. Undoubtedly, it is vital as a discipline that studies the real and important phenomenon of our world - economic reality . She strives for provisency and formalization, she has a lot of mathematics, sometimes complex and interesting. However, having opened a serious economic textbook, you will most likely find some relatively simple calculations, ready-made recipes and tons of informal reasoning in this spirit: "... But in fact, everything may not be the case as you like, if there is the will of key players or government." In the end, sometimes there is a feeling that in this discipline intuition, knowledge of psychology and the ability to perceive the general context are more important than the exact calculation and a meticulous consideration of details (we are talking about the economy, and not about accounting). Finally, in our time, almost half of the linden dissertations is written precisely in the economy, which means that it is not so difficult to scientifically talk on such topics. We will also try our forces in this field, since the injustice of this world is so acute anywhere, as in the issue of distribution of wealth. In addition, whatever the person does, no matter what profession he owned, he is involved in the economy and its game. From its laws, as well as from the laws of physics or mathematics, not to hide anywhere.

Of the entire mass of tasks solved by the mathematical economy, we will consider only one - as it turns out that even under equal conditions for all market participants and fair exchange of the poor means becomes more than the rich, and why even the ideal mathematical society is prone to financial inequality. Well, of course, we learn something new and useful about the distributions of random values.
