Equalitarian Societies are Economically Impossible

The inequality of wealth distribution is a universal phenomenon in civilized nations and it is often imputed to the Matthew effect, that is, the rich get richer and the poor get poorer. Some philosophers unjustified this phenomenon and tried to put the human civilization upon the evenness of wealth. Noticing the facts that 1) the emergence of centralism is the starting point of human civilization i.e., people in a society were organized hierarchically and 2) the inequality of wealth emerges simultaneously, this paper proposes a wealth distribution model based on the hidden tree structure from the viewpoint of complex network. This model considers the organized structure of people in a society as a hidden tree, and the cooperation among human beings as the transactions on the hidden tree, thereby explaining the distribution of wealth. This model shows that the scale-free phenomenon of wealth distribution can be produced by the cascade controlling of human society, that is, the inequality of wealth can parasitise in the social organizations, such that any actions in eliminating the unequal wealth distribution would lead to the destruction of social or economic structures, resulting in the collapse of the economic system, therefore, would fail in vain.
