Society has too many members who are willing to live on the labor of
others, like the shoveler duck described in this extract:
One of the ducks has learned a convenient trick for getting his
dinner. Some of the diving brotherhood who feed under water stir
up a great deal that floats, and the shoveler, preferring to
take his provision from the surface, follows his diving neighbor
to the feeding-place, and while the feeders below stir up the
inhabitants, he swims around on the surface and catches whatever
floats.--OLIVE THORNE MILLER, “The Bird Our Brother.”
