The Advantage of "Comparative Advantage"
There are always minorities, either people or enterprises, that have absolute advantage in a field; the majority apply their comparative advantage to professions where they do their best to be effective players. Based on comparative advantages, different divisions are formed as international trade and the globalized economy develop.
Oranges are flourishing in Florida in the United States, for example, shoes are made perfectly in Wenzhou of China, and people in both areas need oranges and shoes. In Wenzhou, one could try to create an artificial environment for citrus trees of an international standard, and in Florida workers could be trained to make shoes as effectively as workers in Wenzhou using the same resources. However, the costs would be too high. The best solution, therefore, is to allow each location to specialize in its own product, producing enough to meet local needs and exporting the rest. As a result, people in both areas end up with lower cost and higher quality goods than if each tried to produce both. It is self-evident that absolute advantage occurs in this process.
However, absolute advantage may not necessarily apply everywhere. For instance, I know a capable company boss, who is also an expert in private cars and very skillful at changing car oil, even more efficiently than a mechanic. But, almost every time he drives his car to a garage to have the oil changed by a mechanic since he believes he can use the time to do something more valuable. What he uses here is his comparative advantage rather than absolute advantage.
The same rationale may also apply to individual careers. You may not be the best in a certain area, but still have a comparative advantage, which will not be reduced in relation to others' absolute advantage, and you can still find an advantaged position in which your disadvantages is smaller relative to others.
An ordinary talent can, therefore, achieve outstanding results by rightfully exploring his or her comparative advantage. In this sense, we may say that comparative advantage really works.
