Because we think ourselves far above the ape relations,we have let the instincts of the jackal drive our history. Just like animals we compete for mates, we have built civilization, the fundamentals of economics, families and war on the basis of sexual competition.
Language, reason and rational thought is what separates us from other animals, yet for most of our history we have not used these skills other than to take advantage of the other. We have distorted our history in order to dominate over a servant class, and to promote slavery as a social construct.
We act and live out our lives according to what we believe. Since our beliefs are based on false premises, we produce a dysfunctional society. If we correct this problem, all other problems will go away.
