From the article: "It's plenty obvious that free commerce is not a zero-sum game. I go to the liquor store to buy beer. I buy five bottles of Staropolskie Zlote for about ten bucks. I value the beer more than I value the ten bucks -- else I wouldn't have given the clerk my money. The liquor store values my ten bucks more than the beer -- else they wouldn't have sold it to me. We both come away from the exchange happier: I have my beer, they have their money. We both get what we wanted. The world is, in fact, a better place after that exchange than it was before... at least for me and for the liquor store."

From the article: "One firm adds value by trucking the beer from the brewery to a port. Another firm adds value by shipping the beer across the Atlantic. A third firm adds value by shipping the beer across Canada, and yet a fourth firm adds value by providing a broad selection of beers in a relatively convenient place for my buying pleasure."

Congratulations. You've discovered Pareto efficiency ( http://en.wikipedia.org/wiki/Pareto_efficiency ), the means by which goods are distributed.
