I would agree with your theory a little more if the European power brokers didn't start carving up the Austro-Hungarian and Ottoman empires under the watchful eye of Woody Wilson. And they took the German representatives on a lengthy tour of war desolation with the clear objective of making it known that "All this is your fault!" There was a clear desire for severe punishment of the German people and an elitist attitude toward the "Barbarians"
But if the main purpose was to deprive Germans of hope and destroy Germany, the Allies could have permanently occupied large portions of Germany.
