From Don Boudreaux

There are two kinds of people in the world.  Members of the first group think of jobs as being rather like boxes, each of which has a monetary figure on it as well as a set of levers inside.  A job-holder occupies a box, yanks on the box's levers, and in return receives pay in the amount of the prescribed monetary figure.  Lucky workers are those who land in boxes paying big money and whose levers are easy to manipulate; unlucky workers are those who find themselves in boxes paying little money and whose levers are difficult to manipulate.

The second group of people in the world understand that real jobs are a matter of creating value for buyers.  The greater the amount of value I create for others, the better -- or, at least, the higher-paying -- is my job.  In markets, your job isn't a box that you get assigned to; your job is an opportunity to perform, to help improve the lives of others and, in return, to persuade these others to help you improve your life.
