We may have different subsidiary needs, for example, the quantity of a certain vitamin to overcome a nutritional deficiency or specialized help for a mental or emotional problem. But our basic needs are the same. What is different is the way we try to fulfill these needs, i.e. whether we are acting right or wrong, whether our desires and drives are actually leading to real need fulfillment or rather to the defeat of same. One group wars on another. A second group trades.
Trading is a giant step up from killing.
Yet if one trading group cheats another, conflict ensues. Because, although both groups are trying to survive, one is trying to survive at the unfair expense of the other. The cheated group s survival is threatened. Its primary goal has been interfered with. To avoid such conflict, therefore, people must understand the primary goal of survival in terms of all people, not only for themselves and their own family or kind or nation.
