One of the original founders of the Federal Reserve was Paul Warburg, who represented the Rothschild and Warburg families of Europe. He was a member of M. M. Warburg and Company, which had offices in Germany, Amsterdam, and the Netherlands. His brother Max Warburg was the financial advisor to the Kaiser before World War II and was director of the Reichsbank of Germany. Both Warburgs were anti-gold. They argued for an elastic money supply that could be expanded and contracted to accommodate the needs of business. They were for fiat money. Of course, this generally leads to inflation, which is a silent tax on the middle class and savers. The devastating results of the Warburg monetary philosophy was historically displayed in Germany. Max, a Jewish man, fled Germany in 1938—but only after hyperinflation had set in. The brothers' philosophy of currency is playing out today in America as the Fed pumps trillions of dollars into our economy.
