If we lived in a rational world. Were there a rational species only Darwinian simplicity might suffice.
Human beings are not rational beings. Most of us might live to think we are, but that is untrue.
Markets reflect emotions, rational characteristics and superficial inferences. Even the very existence of Tesla, the object of our devotion, would never have happened with purely rational decisions.
An old, perhaps even true, Albert Einstein allegedly said :
"Only two things are infinite, the universe and human stupidity, and I'm not sure about the former."
How can anyone imagine rational markets can exist?
