People do not cooperate under the division of labor because they love or should love one another. They cooperate because this best serves their own interests.
Ludwig von MisesAs society is only possible if everyone, while living his own life, at the same time helps others to live; if every individual is simultaneously means and end; if each individual's well-being is simultaneously the condition necessary to the well-being of others, it is evident that the contrast between I and thou, means and end, automatically is overcome.
