COMPARATIVE ADVANTAGE: The ability to produced one good at a relatively lower opportunity cost than other goods. While pointy-headed economists developed this idea for nations, it's extremely important for people. A comparative advantage means that no matter how good (or bad) you are at producing stuff, there's always something that you're best (or least worst) at doing. Moreover, because you can produce this one thing by giving up less than what others give up, you can sell it or trade it to them. This idea of comparative advantage means that people and nations can benefit by specialization and exchange. You do what you do best, then trade to someone else for what they do best. Both sides in this trade get more and are thus better off after than before.
