Our social systems are a product of the interactions between ourselves and those around us. Human nature dictates what is involved in these interactions. Therefore, one could argue that all social systems are products of human nature.
Inequality is inherent in any biological system. Some organisms in a system will have greater fitness (ability to thrive and reproduce) than others. In a capitalist system, the requirements for fitness are quite different from what you would find in a communal tribal setting, but hierarchy can be found in either setting.
There will always be leaders, those who wish to be leaders, and everyone else. In order to increase their own fitness, leaders may be oppressive.
The most important thing is that a culture institutes checks on the leaders to prevent them from becoming oppressive.
Inequality is, I believe a part of our human instincts.
Human instincts make us thrive to be better than others, I mean who really wants to lose a race, or a game, no we want to win.
This makes us socially not accept one another because we may feel that we are better than someone than they are not worthy.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
