In the instinct to survive those who are able to dominate the competition go about their activities as if others (humans and non-humans) did not matter or did not have interests. Selfishness becomes more prevalent as a people move from elementary economic systems to modern economic systems. The major reason why economic systems collapse is human selfishness. Despite all the achievements in science and technology, there are still poor people in the world and environmental cataclysms have become daily occurrences. This is because the would-be agents of development, such as Multinational Corporations and states, are largely motivated by selfishness. Unfortunately, poor economies pursue development using borrowed models formulated for selfish reasons. Needless to say, the solution to current economic and environmental challenges does not lie in abstract economic jargons or more advanced technological machinery but in taming the evil of human selfishness. This book makes a strong case for a vaccine against the virus of selfishness, namely, education for altruistic egoism.
