I am interested in the various interpretations of Keynes on the long   
term.  Am I jumping in way too late?  (As a non-economist) I had   
always interpreted Keynes's remark (totally out of context) as being   
opposed to those economists whose response was always that in the   
long run everything balances out, or everything clears, or everything   
turns out fair (i.e., if we just let the free market, whatever that   
is, do its job).  
  
And so, in fact, Keynes was the moral one, saying that you need to   
think about the real lives of real people, and the "long-view"   
economists were the immoral ones, because if in the long run (the   
next century or so) everything balances, nonetheless in the meantime   
hundreds of millions of people are suffering.
