French economist/philosopher Frederic Bastiat (1801–50) gave a test for immoral government acts: “See if the law benefits one citizen at the expense … - Walter E. Williams

I personally believe that economics is fun and valuable. People who say they found it a nightmare in college just didn't have a good teacher-professor. I became a good teacher-professor as a result of tenacious mentors during my graduate study at UCLA. Professor Armen Alchian, a very distinguished economist, used to give me a hard time in class. But one day, we were having a friendly chat during our department's weekly faculty/graduate student coffee hour, and he said, "Williams, the true test of whether someone understands his subject is whether he can explain it to someone who doesn't know a darn thing about it." That's a challenge I love: making economics fun and understandable.

Since it's not considered polite, and surely not politically-correct to come out and actually say that greed gets wonderful things done, let me go through a few of the millions of examples of the benefits of people trying to get more for themselves. There's probably widespread agreement that it's a wonderful thing that most of us own cars. Is there anyone who believes that the reason we have cars is because Detroit assembly line workers care about us? It's also wonderful that Texas cattle ranchers make the sacrifices of time and effort caring for steer so that New Yorkers can have beef on their supermarket shelves. It is also wonderful that Idaho potato growers arise early to do back-breaking work in the hot sun to ensure that New Yorkers also have potatoes on their supermarket shelves. Again, is there anyone who believes that ranchers and potato growers, who make these sacrifices, do so because they care about New Yorkers? They might hate New Yorkers. New Yorkers have beef and potatoes because Texas cattle ranchers and Idaho potato growers care about themselves and they want more for themselves. How much steak and potatoes would New Yorkers have if it all depended on human love and kindness? I would feel sorry for New Yorkers. Thinking this way bothers some people because they are more concerned with the motives behind a set of actions rather than the results. This is what Adam Smith, the father of economics, meant in The Wealth of Nations when he said, "It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interests."

We're all grossly ignorant about most things that we use and encounter in our daily lives, but each of us is knowledgeable about tiny, relatively inconsequential things. For example, a baker might be the best baker in town, but he's grossly ignorant about virtually all the inputs that allow him to be the best baker. What is he likely to know about what goes into the processing of the natural gas that fuels his oven? For that matter, what does he know about oven manufacture? Then, there are all the ingredients he uses -- flour, sugar, yeast, vanilla and milk. Is he likely to know how to grow wheat and sugar and how to protect the crop from diseases and pests? What is he likely to know about vanilla extraction and yeast production? Just as important is the question of how all the people who produce and deliver all these items know what he needs and when he needs them. There are literally millions of people cooperating with one another to ensure that the baker has all the necessary inputs. It's the miracle of the market and prices that gets the job done so efficiently. What's called the market is simply a collection of millions upon millions of independent decision makers not only in America but around the world. Who or what coordinates the activities all of these people? Rest assuredly it's not a bakery czar.
