Wall Street and the Rise of Hitler by Anthony C. Sutton:
‘The contribution made by American capitalism to German war preparations can only be described as phenomenal. It was certainly crucial to German military capabilities... Not only was an influential sector of American business aware of the nature of Naziism, but for its own purposes aided Naziism wherever possible (and profitable) - with full knowledge that the probable outcome would be war involving Europe and the United States.’ Penetrating a cloak of falsehood, deception and duplicity, Professor Antony C. Sutton reveals one of the most remarkable but unreported facts of the Second World War: that key Wall Street banks and American businesses supported Hitler’s rise to power by financing and trading with Nazi Germany. Carefully tracing this closely guarded secret through original documents and eyewitness accounts, Sutton comes to the unsavoury conclusion that the catastrophic Second World War was extremely profitable for a select group of financial insiders. He presents a thoroughly documented account of the role played by J.P. Morgan, T.W. Lamont, the Rockefeller interests, General Electric Company, Standard Oil, National City Bank, Chase and Manhattan banks, Kuhn, Loeb and Company, General Motors, the Ford Motor Company, and scores of others in helping to prepare the bloodiest, most destructive war in history.
I do not have evidence at hand but if we consider the end purpose (for example the USD becoming the world's reserve currency) this scenario would not be out of bounds. This is almost like content creators pushing their favorite stock, cryptocurrency or precious metals to their followers because they are heavily invested in it. So, if the scenario materializes (said crypto goes up) they will mostly benefit from it as they are invested in that asset. By the same thought process Blackrock maybe pushing for China's dominance over USA because they are heavily invested in it. But let's not digress...In the case of the US institutions you mentioned they would massively benefit if the USD became the world's reserve currency...
