I mean everyone knows Keynesian by itself can't explain/solve everything (Breton Woods System collapse and Oil shocks of 1973). But Neo-Keynesian combined with monetarism does the job pretty well for the most part.

Does it?  
  
 The genius of Keynesian theory is that the money is spent at the top before it loses it's value in the market. By the time it reaches the consumer, the value is adjusted by the market. 
  
 We took it two or three steps further and now the zero day money value surplus, aka real value, is wasted on debt interest. 
  
 No matter what, the consumer pays the price.
