David Ricardo famously demonstrated how England and Portugal both benefit by specializing and trading according to their comparative advantages, Portugal with wine and England with cloth.Nevertheless, they benefit from trade thanks to their comparative advantages and disadvantages.Suppose the attorney produces 5/hr in legal services and /hr in secretarial duties.Specializing and trading along these lines benefits each.People learn their comparative advantages through wages.This drives people into those jobs they are comparatively best at.If a skilled mathematician earns more as an engineer than as a teacher, he and everyone he trades with is better off when he practices engineering.
