What a Growing Economy Does to Jobs: New at Reason

In South Africa, people who speak Afrikaans use the word “robot” to mean the same thing it means in English. But it is also the word for “traffic light.” Why? Before automated signals, motorists on busy streets were directed by police officers standing on platforms. Those cops were automated out of a job.

This bit of trivia comes from the dazzling new book Bourgeois Equality: How Ideas, Not Capital or Institutions, Enriched the World, by University of Illinois at Chicago economist and historian Deirdre McCloskey. She points out that automation and robots are nothing new, that they are crucial to raising living standards and that the jobs they destroy are always replaced by better ones.
