Rothbard explains how money was originally developed, and why gold was chosen as the preferred commodity to use as money. The author also explains how the gold standard makes money a commodity, and how market forces create a stable economy. Rothbard shows that many European governments went bankrupt due to World War I and left the gold standard in order to try to solve their financial issues, which was not the right solution. He also argues that this strategy was partially responsible for World War II and led to economic problems throughout the world.
