It is wrong to pick out individual traits of human beings during the capitalist era and fatalistically assume it is the human condition.
Not so. We can pick out plenty of unpleasant human traits during the communist era, both in China and in Eastern Europe and the Soviet Union, and find they are exactly the same as under capitalism. We can look at history as far back as we like to go, and we find that negative traits often brought about the fall of previous societies and civilisations.
Whether we like it or not, it is the human condition here. This is probably because this is a place where beings in many stages of development, and with many different traits of behavior, come to learn through experience. It is therefore inevitable that all our worst human traits will be present, as well as our best ones, complete with everything in between.
