You want to change the world? There is one thing that has changed the world more than any other in the last 500 years. It is the least-noticed thing of all: commerce. Through commerce, we are fed. Through commerce, we are clothed. Through commerce, we are healed. We are entertained. We communicate. We care for those we love. We are given the power to shape our lives. Through commerce, we find ever better ways of living and grappling with this strange curse that has always afflicted the world: namely that there is never enough. Commerce is the only force that has ever been discovered to alleviate our material plight, to convert a grueling shortage of anything and everything into a glorious abundance of anything and everything. It is the thing that defines us, liberates us, empowers us, ennobles us.
