So Harry Pollard suggests, going on to note that earlier economists   
talked of wealth, which has now become incredibly complex to define.  
  
But everyone who is not in economics (and perhaps some who are)   
recognize that "voluntary" is not such a simple term.  Marx, JSMill   
(in the power of public opinion in On Liberty), Freud and other   
psychologists, Foucault -- the list of those who raise questions   
about the meaning or content of "voluntary" is legion.  
  
Similarly, indeed, there are many who wonder about involuntary.  Even   
those who are coerced act in many cases with some degree of   
voluntariness.  After all, Jack Benny knew that he had a choice when   
an armed robber threatened him with, "Your money or your life!"
