Calling the bottom of a river a “bed” is a metaphor. Imagine the river restlessly sleeping on its muddy mattress. But when we’ve so internalized a metaphor that we forget it is a figure of speech, as with the phrase “river bed,” it is called a “dead metaphor.”
Labor Day is, alas, akin to a dead metaphor in contemporary America. There was a time when, as in 1936, the unionized auto workers could make effective demands from their employers, for higher wages and better working conditions. Workers no longer get better off in today’s U.S.A. They are often summarily dismissed if they try to unionize. They are badly paid. Good jobs have been switched out for bad jobs. Tax policy has been manipulated by the wealthy and corporations, who have bought Congress and state legislatures, so as to ensure that the rich get richer, and richer and richer.
