167 A Fountain of Greenbacks
There used to be mechanics that tried to make perpetual motion by combinations of wheels, shifting weights, and rolling balls; but somehow the machine would never quite run. A perpetual fountain of greenbacks, of wealth without labor, is just as foolish as a fountain of eternal youth. The idea that you can produce money without labor is just as foolish as the idea of perpetual motion. They are old follies under new names.
