What human motivation is responsible for getting the most wonderful things done? I would say greed. When I use the term greed, I do not mean cheating, stealing, fraud and other acts of dishonesty, I mean people seeking to get the most for themselves. One might be tempted to use "enlightened self interest” but I like greed better. Unfortunately, many people are naive enough to believe that it is compassion, concern, and "feeling another's pain" that's the superior human motivation. As such we fall easy prey to charlatans, quacks and hustlers.
