A person has a comparative advantage at producing something if he can produce it at lower cost than anyone else.Having a comparative advantage is not the same as being the best at something. Someone who is the best at doing something is said to have an absolute advantage.
The thing is, as with many other masculine insecurities, this is predominantly in our heads. Worse, I’m the shortest of all my friends who range from 5’1o” on the short side, to 6’7″ on the tall side.

Someone may have an absolute advantage at producing every single thing, but he has a comparative advantage at many fewer things, and probably only one or two things.
