An employer of labor is on the average more intelligent than a laborer

Context

“If there existed such a thing as a really national education or a trustworthy system of general examination, education might be tested directly. In the absence of these, the nature of a person's occupation is some test. An employer of labor is on the average more intelligent than a laborer; for he must labor with his head, and not solely with his hands. A foreman is generally more intelligent than an ordinary laborer, and a laborer in the skilled trades than in the unskilled. A banker, merchant, or manufacturer is likely to be more intelligent than a tradesman, because he has larger and more complicated interests to manage.” source
