Its called evolution.
The odds are stacked against the weakest, that via the course of life, where chance, luck and randomness play a part, the old and weak die, the new are born, the group slowly become better formed to excel inside the environment where it resides.
Actually, I've read that the principle of cooperation has proved more effective than outright dog-eat-dog competition.
Certainly true of few organisms (ant colonies, social animals like chimps, wolves, humans), though even that group "setting" was all random, which is how we end up with cross-species dependency in some instances. The individual's best chance at survival was through success in cooperating with others, many times unbeknownst to the organism. Even then, there are outliers that break the mold (psychopaths, hermits, lone wolves, etc..) and carry their genes forward.
Traders?Scientists don't (no pun intended) randomly slap the word chaotic on whatever they don't understand. They appear to be random but actually are just dynamic - "the keys to the kingdom". One only has to look harder for the underlying pattern.
