Likewise, the banking consortium Morgan set up would be bankrupt in the case of CP victory. Whether we like it or not, the people who
owned the US economy were invested in taking their money back and become the dominant financial cast in the globe. If there was substantial trade with the CP and the Americans hoped to obtain their assets, only then the situation would be different. Wilson indeed didn't want to participate in the war but what about those who had the actual power?
In general, France was able to increase their fiscal resources from 7,846 billion francs in 1918 to 12,515 billion in 1919. It is important to state that this increase came from indirect taxes and monopolies ( post office, matches, tobacco, powder, telephone and telegraph, etc). Indeed in spring 1917 the foreign assets of France were running short. However, the gold and silver reserves remained
in France.
